10 Secrets of Ice Cream Truck Drivers

Ever since Good Humor founder Harry Burt dispatched the first jingling ice cream trucks in Youngstown, Ohio, in 1920, kids and adults alike have had a primal reaction to the sight of a vehicle equipped with a cold, sugary payload. Today, ice cream trucks spend May through October hoping to entice customers into making an impulse beat-the-heat purchase. To get a better idea of what goes into making ice cream a portable business, Mental Floss spoke with several proprietors for their take on everything from ideal weather conditions to police encounters. Here’s the inside scoop.

1. IT CAN GET TOO HOT FOR BUSINESS.

The most common misconception about the ice cream truck business? That soaring temperatures mean soaring profits. According to Jim Malin, owner of Jim’s Ice Cream Truck in Fairfield, Connecticut, record highs can mean decreased profits. “When it’s really hot, like 90 or 100 degrees out, sales go way down,” Malin says. “People aren’t outside. They’re indoors with air conditioning.” And like a lot of trucks, Malin’s isn’t equipped with air conditioning. “I’m suffering and sales are suffering." The ideal temperature? "A 75-degree day is perfect.”

2. THEY DON’T JUST WANDER NEIGHBORHOODS ANYMORE.

The days of driving a few miles an hour down a residential street hoping for a hungry clientele have fallen by the wayside. Many vendors, including Malin, make up half or more of their business by arranging for scheduled stops at events like weddings, employee picnics, or school functions. “We do birthday parties, church festivals, sometimes block parties,” he says. Customers can pay in advance, meaning that all guests have to do is order from the menu.

3. SOME OF THEM DRIVE A MINIBUS INSTEAD OF A TRUCK.

For sheer ice cream horsepower, nothing beats a minibus. Laci Byerly, owner of Doodlebop’s Ice Cream Emporium in Jacksonville, Florida, uses an airport-style shuttle for her inventory. “Instead of one or two freezers, we can fit three,” she says. More importantly, the extra space means she doesn’t have to spend the day hunched over. “We can stand straight up.”

4. THEY HAVE A SECRET STASH OF ICE CREAM TO GIVE AWAY TO SPECIAL CUSTOMERS.

The goal of any truck is to sell enough ice cream to justify the time and expense of operation, so freebies don’t make much sense—unless the truck happens to have some damaged goods. Malin says that it’s common for some pre-packaged bars to be broken inside wrappers, rendering them unattractive for sale. He sets these bars aside for kids who know the score. “I put them in a little box for kids who come up and ask if I have damaged ice cream,” he says. “Certain kids know I have it, and I’m happy to give it to them.”

5. THEY’RE CREATING CUSTOM ICE CREAM MENUS.

While pre-packaged Popsicles and ice cream sandwiches remain perennial sellers, a number of trucks are mixing up business by offering one-of-a-kind treats. At the Chunky Dunks truck in Madison, Mississippi, owner Will Lamkin serves up Ice Cream Nachos, a signature dish that outsells anything made by Nestle. “It’s cinnamon sugar chips with your choice of ice cream,” he says. “You get whipped cream, too. And for the ‘cheese,’ it’s a caramel-chocolate sauce.” The nachos work because they’re “streetable,” Lamkin’s label for something people can carry while walking. “The next seven or eight people in line see it, and then everyone’s ordering it.”

6. THEY DON’T ALWAYS PLAY THE ICONIC JINGLE.

Before most people see an ice cream truck, they hear that familiar tinny tune. While some operators still rely on it for its familiarity, Malin and others prefer more modern tracks. “Normally we play ‘80s rock,” he says. “Or whatever we feel like playing that day. We rock it out.”

7. POP CULTURE CHARACTERS ARE SOME OF THEIR BEST SELLERS.

While adult customers tend to favor ice cream treats they remember from their youth, kids who don’t really recognize nostalgia tend to like items emblazoned with the likenesses and trademarks of licensed characters currently occupying their TV screens and local theaters. “Characters are the most popular with kids,” Byerly says. “SpongeBob, Minions, and Captain America.”

8. THEY KEEP DOG FOOD HANDY.

At Doodlebop’s, Byerly has a strategy for luring customers with pets: She keeps dog treats on hand. “The dog will sometimes get to us before the owner does,” she says. “If the dog comes up to the truck, he’ll get a Milkbone.” That often leads to a human companion purchasing a treat for themselves.

9. SOMETIMES RIVALS WILL CALL THE COPS.

Though there have been stories of rogue ice cream vendors aggressively competing for neighborhood space over the years, Malin says that he’s never experienced any kind of out-and-out turf war. Ice cream truck drivers tend to be a little more passive-aggressive than that. “I have a business permit for Fairfield, so that’s typically where I’m driving,” he says. “But sometimes I might go out of town for an event. Once, a driver pulled up to me and asked if I had a permit. I said ‘No, I’m just here for an hour,’ and he said, ‘OK, I’m calling the cops.’ They try and get the police to get you out [of town].” Fortunately, police typically don’t write up drivers for the infraction.

10. SOME LUCKY CUSTOMERS HAVE AN APP FOR HOME DELIVERY.

Technology has influenced everything, and ice cream trucks are no exception. Malin uses an app that allows customers to request that he make a special delivery. "People can request I pull up right outside their home," he says. If their parents are home, there’s one additional perk: "I accept credit cards."

Meet Ice Cream Scientist Dr. Maya Warren

Maya Warren
Maya Warren

Most people don’t think about the chemistry in their cone when enjoying a scoop of ice cream, but as a professional ice cream scientist, Dr. Maya Warren can’t stop thinking about it. A lot of complex science goes into every pint of ice cream, and it’s her job to share that knowledge with the people who make it—and to use that information to develop some innovative flavors of her own.

Unlike many people’s idea of a typical scientist, Warren isn’t stuck in a lab all day. Her role as senior director for international research and development for Cold Stone Creamery takes her to countries around the world. And after winning the 25th season of The Amazing Race in 2014, she’s now back in front of the camera to host Ice Cream Sundays with Dr. Maya on Instagram. In honor of National Ice Cream Month this July, we spoke with Dr. Warren about her sweet job.

How did you get involved in food science?

I fell in love with science at a really young age. I got Gak as a kid, you know the Nickelodeon stuff? And I remember wanting to make my own Gak. I remember getting a little kit and putting together the glue and all the coloring and whatever else I needed to make it. I also had make-your-own gummy candy sets. So I was always into making things myself.

I didn't really connect that to chemistry until later on in life. When I was in high school, I fell in love with chemistry. I decided at that point I should go to college to become a high school chemistry teacher. One day I was over at my best friend's house in college, and she had the TV on in her apartment. I remember watching the Food Network and there was a show on called Unwrapped, and they go in and show you how food is made on a manufacturing, production scale. In that particular episode, they went into a flavor chemistry lab. It was basically a wall full of vials with clear liquid inside them. They were about to flavor soda to make it taste like different parts of a traditional Thanksgiving meal. So you had green bean casserole-flavored soda, you had turkey and gravy-flavored soda, cranberry sauce soda. And I was like, "Oh my gosh, like how disgusting is this? But how cool is this! I could do this. I'm a chemist."

I love the science of food and how intriguing it is, and I had to ask myself, "Maya, what do you love?" And I was like, "I love ice cream! I’m going to become one of the world’s experts in frozen aerated deserts." I found a professor at UW Madison [where I earned my Ph.D. in food science], Dr. Richard Hartel, and he took me under his wing. Six and half years later, I’ve become an expert in ice cream and all its close cousins.

How did you arrive at your current position?

I didn't actually apply for the job. Six years ago, I was running The Amazing Race, the television show on CBS. After I was on it, a lot of publications reached out wanting to interview me. I did a couple of interviews and someone from Cold Stone found my interview. They noticed that I’m a scientist, and they were looking for someone with my background, so they reached out to me. I was actually writing my dissertation, and I was like, "I'm not looking for a job right now. I just want to go home and sleep."

I originally told myself I wasn't going to work for a year because I was so exhausted after graduate school and I needed some time off. But I ended up going to their office in Scottsdale for an interview. At that time, I still wasn't sure if was going to do it or not because I didn't want to move to Arizona. It's just so incredibly hot. I ended up being able to work something out with them where I didn't have to move Arizona. I came on board back in 2016. I started as a consultant at first because I didn't want to move. But then I proved I could make this work from afar.

What does your job at Cold Stone Creamery entail?

I'm the senior director for international research and development for Cold Stone Creamery. A lot of what I do is establishing dairies and building ice cream mixes for countries all across the globe. Dairy is a very expensive commodity. Milk fat is quite pricey. Cold Stone has locations all over the world, and they all need ice cream mixes. But sometimes bringing that ice cream from the United States into that country is extremely expensive, because of conflicts, because of taxes, different importation laws. A lot of what I do is helping those countries figure out how they can build their own dairies, or how can they work with local dairies to make ice cream mixes more affordable.

The other part of what I do is create new ice cream flavors for these places. I look at a local ingredient and say, "I see people in this country eating a lot of blank. Why don’t we turn that into ice cream? How would people feel about that?" I try to get these places to realize that ice cream is so much more than a scoop. In the States, we have ice cream bars, ice cream floats, ice cream sandwiches. But many countries don’t see ice cream like that. So getting these places to come on board with different ideas and platforms to grow their business is a big part of my job.

What’s your favorite ice cream flavor you made on the job?

I made a product called honey cornbread and blackberry jam ice cream. Ice cream to me is a blank canvas. You can throw all kinds of paint at it—blue and red and yellow and orange and metallic and glitter and whatever else you want—and it becomes this masterpiece. That's how I look at ice cream.

Ice cream starts out with a white base that's full of milk fat and sugar and nonfat dry milk. It’s plain, it’s simple. For this flavor, I thought, "Why don’t I throw cornbread in ice cream mix?" I put in some honey, because that’s a good sweetener, and a little sea salt, because salt elevates taste, especially in sweeter desserts. And why don’t I use blackberry jam? When you’re eating it, you feel the gritty texture of cornbread, which is quite interesting. You get that pop of the berry flavor. There’s a complexity to the flavors, which is what I enjoy about what you can do with ice cream.

What is the most rewarding part of your job?

One of the most rewarding things is being able to produce a product and see people eat it. The other part of it is being able to have a hand in helping people in different countries get on their feet. Ice cream isn’t a luxury for many people in America, but there are people in other countries that would look at it that way. Being able to introduce ice cream to these countries is fascinating to me. And being able to provide job opportunities for people, that sincerely touches my heart.

The last part is the fact that when I tell people I’m an ice cream scientist, it doesn’t matter how old the person is, they can’t believe it. I’m like, "I know, could you imagine doing what you love every day?" And that’s what I do. I love ice cream.

What are some misconceptions about being an ice cream scientist?

When I tell people what I do, they automatically think I just put flavors in ice cream. They don’t know that there’s a whole other part of it before you get to adding flavor. They don't think about the balancing of a mix, the chemistry that goes into ice cream, the microbiology part that goes into ice cream, the flavor science that goes into ice cream. There’s so much hardcore science that goes into being an ice cream scientist. Ice cream, believe it or not, is one of the most complex foods known to man (and woman). It is a solid, it’s a gas, and it’s also a liquid all in one. So the solid phase comes in via the ice crystals and partially coalesced fat globules. The gas phase comes in via the air cells. Ice cream usually ranges from 27 to 30 percent overrun, which is the measurement of aeration in ice cream. You also have your liquid phase. There’s a semi-liquid to component to ice cream that we don’t see, but there’s a little bit of liquid in there.

People don’t think about ice crystals and air cells when they think about ice cream. They really don’t think partially coalesced fat globules. But it’s really fun to connect the science of ice cream to the common knowledge people have about this product they eat so much.

If you weren't doing this, what would you be doing?

If I wasn’t an ice cream scientist, I think that I would have been a motivational speaker. When I was a kid, my parents would send me to camp, and I remember having a lot of motivational speakers that would come in and talk to us. I always wanted to do that as a kid. So it’s either between that or a sport medicine doctor, because that was the track I was on in college. So if I didn’t figure out food science, I probably would have gone back to sports medicine. But I’m glad I didn’t go down that path, because I think I have one of the coolest and sweetest jobs—pun intended—that exists on planet Earth.

You’ve been hosting Ice Cream Sundays on Instagram Live since May. What inspired this?

At the beginning of quarantine, I was like, "What am I going to do? I can't travel anywhere. What am I going to do with all this extra time?" I was on Instagram, and I started seeing people at the very beginning of this make all this bread. And I was like, "I need to start talking about ice cream more. Ice cream can’t be left out of this conversation."

I started making ice cream and posting here and there, and people would ask me about it, and I would ask them, "Do you have an ice cream maker?" I put a poll up and 70, 80 percent of people who replied did not have ice cream makers. So I was like, "How am I going to make people happy with ice cream if all I do is show photos and they can’t make it?" Then I decided to make a no-churn ice cream. That’s not how you make it in the industry, but it’s how you make it at home if you don’t have an ice cream machine. I think it was around May 3, I decided I was going to do an Instagram Live. I’m going to call it Ice Cream Sundays with Dr. Maya, and I’ll just see where it goes from there.

I did one, and from the beginning, people were so in love with it. Then I thought, "Whoa, I guess I should continue doing this." I’ve made a calendar. People really attend. People make the ice cream. People watch me on Live. I’ve always wanted to have a television show on ice cream. I figured, if I can’t do a show on ice cream right now on a major network, I might as well start a show on Instagram.

What advice do you give to young people interested in becoming ice cream scientists?

My advice is: If you want to do it, do it. Don’t forget to work hard, but have fun along the way. And if ice cream isn’t necessarily the realm for you, make sure whatever you do makes your heart flutter. My heart flutters when I think about ice cream. I am so intrigued with it. So if you find something that makes your heart flutter, no one can ever take away your desire for it. If it is ice cream, we can get down and dirty with it. I can tell them about the science behind it, the biology, the microbiology that goes into ice cream itself. But I just encourage people to follow their heart and have fun with whatever they do.

What’s your favorite ice cream flavor?

If we’re talking just general flavors, I love a good cookies and cream. I’m an Oreo fan. I also make a double butter candy pecan that is my absolute jam.
