This Saturday is National Mustard Day, and condiment brand French’s is reinforcing its “Not From France” campaign by celebrating in a quintessentially American way: with a seemingly disgusting food mashup. According to a press release, the company has partnered with edgy ice cream brand Coolhaus to bring you mustard—yes, mustard—ice cream.

If you live in New York City or Los Angeles, you can try it in person. The Coolhaus shop in Culver City, Los Angeles, will carry it from August 2 to August 4 and again from August 9 to August 11. In New York, you can catch the French’s Mustard Ice Cream truck at select street corners throughout Manhattan, Brooklyn, and the Hamptons from August 1 to August 3. And, if you thought you could pass off your frankly alarming flavor selection as just a deeply golden French vanilla, think again—the ice cream is served in a festive cup plastered with the words “mustard ice cream.” It also comes with a pretzel cookie to help temper the tang.

French's

For those of you who find your taste buds tingling expectantly at the idea of such an innovative confectionery abomination, French’s has published a mustard ice cream recipe that you can whip up at home, wherever you live.

The recipe may shed some light on just how mustard-y the ice cream actually is. It contains 2 cups of heavy cream, 1 cup of sweetened condensed milk, 1/4 cup each of whole milk and light corn syrup, 2 tablespoons of sugar, 1 tablespoon of vanilla extract, and only 1/4 cup of mustard. Its secret ingredient is one entire teaspoon of yellow food dye (plus a single drop of green coloring). So although the ice cream looks intense, it probably tastes relatively mild.

Who knows? Maybe mustard ice cream will join the ranks of other bizarre-yet-admittedly-delicious food fusions like French fries in milkshakes, maple syrup with bacon, and pineapple on pizza. Coolhaus CEO and founder Natasha Case is optimistic. “As lovers of sweet-meets-savory, pure ingredients, and unique creations,” she said in the press release, “we are incredibly excited to be collaborating with French’s Mustard in creating this one-of-a-kind product. It’s been so fun to explore this classic condiment in a whole new way and create an unforgettable thoughtfully-crafted ice cream flavor with an All-American taste.”
