How do you make Puerto Rican dessert Flan?

To make Puerto Rican flan, start by caramelizing sugar in a saucepan until it turns golden brown, then pour it into a flan mold to coat the bottom. In a separate bowl, blend together eggs, sweetened condensed milk, evaporated milk, and vanilla extract until smooth. Pour this mixture over the caramel in the mold, then bake in a water bath at 350°F for about an hour. Once cooled, refrigerate and then invert onto a plate to serve.
