Conchas are a type of Mexican pan dulce, or sweet bread. Unlike our pastries and donuts, Mexicans eat lightly sweetened breads for breakfast, or as a merienda at night. Conchas, or "shells", are one of our favorite pan dulce, known for their sweet decorative tops. Don't say you like to eat "conchas" to anyone outside of Mexico though, the word takes on different meanings in other countries!
