The only time I really could say that I really liked flan, was back in college when a friend and I made his mom's recipe. She is Columbian and her recipe involved putting all the ingredients in a blender (genius I tell you, no other recipe for flan is as easy as doing that). We baked it in a water bath, cooled it overnight, it turned out pretty spiffy.
I went to make it on my own a few years later as part of a Mexican dinner for some family. I stumbled upon a recipe on allrecipes.com called Creamy Caramel Flan. I make use the directions from my friends mom, and the recipe from this one. Enjoy, it sounds complicated, but it really isn't, and it is a perfect dessert to make ahead of time. As it needs to cool at least 8 hours before serving. It is also an awesome dessert because the ingredients are easy to keep on hand. Bonus it is gluten free, which dessert wise is very uncommon.
