Bake in a 350 degree oven for about an hour. After 1/2 hour has passed check to see if it is done, by inserting a knife into the middle. If the knife comes out clean its done, if not put it back in and wait a little longer. If it starts to darken cover with aluminum foil. Once done let it chill in the refrigerator till cold. After that all you have to do is ENJOY your flan. If you make it please let me know how it comes out.
