Nice recipe, and very original. The association of flavours is very interesting.
Ingredients (for 4 people)
1 orange (or 2-3 mandarins)
350 g ricotta
100 g sugar
1 soup spoon flour
The juice of a lemon
1 teaspoon of citrus fruits zests
Pre-heat the oven at 180°.
Prepare the zests. Peel the grapefruit and the orange (here is a good video if you don't know how to do, click here).
In a salad bowl, pour the ricotta and the egg yolks. Stir well. Add the sugar, the flour, the lemon juice and the zests. Beat the preparation.
Beat the egg whites until they are stiff and add them to the other preparation.
Pour a third of the preparation in the ramekins, place the fruit slices and cover with the rest of the preparation.
Bake for about 40 min.
