💡 What's interesting

Culturally, it's a beloved potluck and holiday staple in the U.S., often associated with easy, no-mixing-bowl baking. Nutritionally, its unique 'magic' comes from the sweetened condensed milk, which caramelizes during baking to create a cohesive, fudgy texture while also providing a concentrated source of calcium and sugar.
