3 C milk
1/2 C sugar
1 tsp vanilla
Mix this all together for pouring in the pan
Caramel sugar for coating the pan
1/2 C sugar melted in a skillet
Stir this frequently. I like using a wooden spatula. You want it a deep amber color, but not burnt. Immediately pour this into the greased pan.
I like using a bundt pan for flan (as you can see, I didn't this time. My recipe amount did not fit this pan. I have to get a new pan). Pregrease it. Heat the oven to 325 degrees. Find a pan the flan pan will fit in and put about 1/2" hot water in it. Pour in the caramelized sugar, it doesn't need to coat the pan, cooking will distribute it. Pour in the flan ingredients. Bake about 1 hour, till a knife inserted in center comes out clean. Remove the pan from the hot water and set on rack to cool. Then refrigerate until cold. I usually get this done in the morning, so I don't have to think about it with meal prep.
When ready to serve, loosen the edges with the tip of a knife. Cover the pan with a large serving plate and invert. It usually releases right away, or will in a bit.
I'd heard that if you make a good dessert, and have a good appetizer, your meal will be a success - like focus on those first.
