Triple Sec

Californian Harry Baker invented the chiffon cake in 1927, but he kept the recipe a tightly guarded secret for another 20 years. He finally relented and sold his formula to General Mills. The mystery ingredient? Vegetable oil, which gave the cake richness and a light, moist texture. We spike this one with all the flavors of a Margarita cocktail; the Strawberry Compote with Tequila and Lime is an elegant touch.

There’s a simple structure behind all sours, a family of citrus-based cocktails.
