Flan De Vermicelle Aux Citrons
Ingredients
Directions
Prepare the base
Rub the lemon rind on the sugar.
Add the sugar to the boiling milk and gradually stir in the vermicelli.
Boil for a few minutes, then add the butter and place over low heat to swell the vermicelli.
Finish and serve
Once cooked, add salt, egg yolks, and whipped cream to soften the mixture.
Fold in the whipped egg whites gently before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vermicelli
- Swells in the hot milk and butter, giving the dish its body and soft texture.
- Egg yolks
- Enrich and thicken the mixture, adding richness and a smooth, set texture.
- Egg whites
- Whipped and folded in, they add lightness and airiness to the dish.
- Butter
- Adds fat for richness and a silky mouthfeel.
- Milk
- Provides liquid that the vermicelli absorbs and swells in, forming the base.
- Sugar
- Sweetens the dish and carries the lemon flavour from the rind.
The step that matters
Fold in the whipped egg whites gently. Whipped egg whites hold air bubbles that give lightness. Stirring vigorously collapses them, so the dessert turns dense instead of airy.
Swap the lemon
