Pre-heat the oven at 400F.
I use a pot that has a removable handle to go in the oven for this dessert.
Start by making a caramel with the sugar and the water on a medium heat. Do not stir it (only to help dissolve the sugar and then stop. Once it is done (golden), off heat, spread it on the side of your pot by making circular movements.
In a bowl, beat the eggs. Add the condensed and evaporated milk. Stir well.
Add the vanilla, in whatever aspect you have it... powder, liquid, for me a bean that I opened the pod and removed the seeds from it by scrapping with a knife. Stir again.
Pour in your pan (or whatever dish you use and have the caramel is at the bottom.
Put in the oven for 35-40 minutes at 400°. To check if it is ready, insert a knife in, if it comes out clean. You've done it!
