In a flan mold, cook the sugar over medium-high heat until it forms the caramel.
Very carefully, distribute the caramel in the bottom and sides of the mold.
Preheat oven to 350˚F.
Blend the rest of the ingredients. Pour in the flan mold and cover well with its lid or with foil and put it in a deep mold, with water to make a bain de Marie.
Bake from 50 minutes to 1 hour, or until a knife inserted in the middle comes out clean.
Allow to cool completely and refrigerate for at least 4 hours before serving (better if all night).
Before serving, gently turn on a platter.
