With the issuance of the new Delicioso Forever stamps, the U.S. Postal Service celebrates the influence of Central and South American, Mexican and Caribbean foods and flavors on American cuisine. The booklet features stamps depicting tamales, flan, sancocho, empanadas, chile relleno, and ceviche.

Flan, also known as crème caramel, is a popular dessert in many parts of the world, including Europe, the Caribbean, the Americas, and the Philippines. A baked custard, its essential ingredients are eggs, milk, and sugar. As a custard bakes, the egg proteins form a network that traps liquid, creating a gel. Recipes for this smooth, creamy treat abound, and for good reason: It’s happy to accommodate substitutions, changes in proportions, and the addition of flavorings, offering many opportunities for experimenting.
