Ranking 10 Peppers on the Scoville Scale

In 1912, pharmacist—and assumed spicy food lover—Wilbur Scoville developed a system for measuring the level of heat in peppers and other spicy by measuring them in Scoville Heat Units, a.k.a. SHU, or the concentration of capsaicin found within them. Here are 10 peppers and how they rank on the Scoville Scale. How many would you be willing to give a try?

1. NAGA JOLOKIA (OR BHUT JOLOKIA) PEPPER

This is about as hot as a pepper gets at 855,000 to 1,050,000 Scoville units. It's not at the very top of the scale because that spot is reserved for pure capsaicin, the component in hot peppers that make them have that "burn." At the time this pepper was tested for the Scoville scale, the Red Savina (see below) was the hottest pepper in the world, and the bhut jolokia was found to be nearly twice as hot as that. It's reported that eating just one seed from this scorcher can make your mouth hurt for up to 30 minutes after you consume it. And you had better not get it in your eyes.

2. RED SAVINA PEPPER

The red savina was specifically grown to be a super-hot chili. Frank Garcia of GNS Spices in Walnut, California invented it (or bred it, I guess, would be more accurate), but people have been having trouble growing the red savina up to the level of hotness Garcia did, even when they have a certified red savina seed. Even so, you can find most red savinas somewhere between 350,000 and 580,000 on the Scoville.

3. HABANERO PEPPER

It's believed to have originated in the Yucatan and has a bit of a citrus flavor to it. The bhut jolokia is often mistaken for a habanero, but you would know the difference as soon as you bit into one. The habanero is only (only) 100,000 to 350,000 Scoville units.

4. DATIL PEPPER

It can be called a sweeter, fruitier version of the habanero. But just because it's sweeter doesn't mean it packs less punch: it can go up to 300,000 units on the Scoville, just like the Habanero can. It can also be milder, going all the way down to 100,000 units. You can find lots of datil peppers in the St. Augustine, Florida, area.

5. ROCOTO (ALSO LOCOTO) PEPPER

It isn't really found in the U.S. too much. It's common in South American countries and used in their cooking quite a bit. And it's so pretty! It can be a fairly mild pepper at 50,000 Scoville units, which is the equivalent of a really spicy cayenne pepper, but they can take you by surprise at 250,000 units as well.

6. CHILTEPIN PEPPER

It grows in Central America, Mexico, and the southwestern U.S. They're just little guys. The pepper is also known as the chile tepin, tepin being a Nahuatl word that means "flea." But don't let their little size fool you! Their heat is intense, measuring between 50,000 and 100,000 Scoville units. But if you can get through the first minute or so, you'll probably be OK: the heat is super strong but subsides quickly.

7. PEQUIN PEPPER

You probably know this pepper, but you may not realize it. It's one of the main ingredients in the cholula sauce you'll often find at Mexican restaurants. It's not too bad, being comparable in heat to the Cayenne at 30,000 to 60,000 Scoville units. But the taste is much different: it's supposed to have a smoky, nutty flavor.

8. CAYENNE PEPPER

It's a bit milder, rating at 30,000 to 50,000 Scoville units. It's named after the French Guiana city of Cayenne. I'm sure you're familiar with the cayenne pepper; it's ground and sold as a pretty common spice. Although it's only halfway down on the scale, it's definitely has some kick to it and is too hot for some people.

9. SERRANO PEPPER

It has just a little more kick than a jalapeño: 10,000 to 20,000 Scoville units. Not bad at all. You can also put some chipotle peppers in this category; a chipotle is really just a jalapeño that has been dried and treated.

10. JALEPENO PEPPER

At 2,500 to 10,000 Scoville units, it's pretty mild compared to the rest of these scorchers.

5 Ingenious Tricks for Saving Burnt Cookies

It doesn’t take long for cookies to go from an irresistible golden brown to a dispiriting black (especially if you're baking at a high altitude). But before you toss them in the trash and start rummaging around in your pantry for a store-bought snack, we have a few suggestions for saving that imperfect batch.

1. Grate off the burnt bits of cookie with a zester or cheese grater.

As PureWow explains, all you have to do is slide the cookie along your cheese grater to get rid of the burnt layer on the bottom. The smaller the holes, the better, so a lemon zester works well for this, too.

2. Scrape the burned part of the cookie off with a knife.

If you don’t have a cheese grater, you can get the same results with a regular knife—it just might take you an extra minute or two. Instead of slicing off the entire bottom of the cookie, hold your knife blade perpendicular to the bottom of the cookie and carefully scrape away the burnt crumbs.

3. Store the burned cookies in a jar with a piece of bread.

Even after you’ve shaved off the blackened evidence of your culinary blunder, your cookies might still be crispier than you’d prefer. Store them in an airtight container with a slice of bread—they’ll soak up the moisture and soften right up.

4. Make ice cream sandwiches with your burned cookies.

Snobby snackers won’t scoff at your grated cookies if they can’t even see the bottoms. Slather one with a nice, thick layer of ice cream, slap another one on top, and roll the edges in your favorite topping for a treat that’s better than any cookie—burnt or not.

5. Transform your burned cookies into a cookie crust.

For charred, crunchy cookies that seem beyond salvation, you can completely cut off the burnt bottoms, crush the remains, and turn them into a cookie crust for a pie or cheesecake. Here’s a simple recipe from the Pioneer Woman that calls for three ingredients: cookie crumbs, butter, and sugar.
