Leche Plan is one of my favorite dessert. It is popular in the Philippines. It is very historic because it was brought to the Philippines at the time we were colonied by the Spaniards. Im not sure if this is true but i heard about the story that Leche flan was made because when Filipinos were building Intramuros they are using the egg whites for it to be very strong. So what they did is they get the yolk of the egg and added milk to it for them to be able to overcome their hunger. And that is how the Leche Flan was made. Main ingredients are egg yolk and eveporated milk.
