Preparation
Step 1
Toast the flour in a dry pan, stirring constantly.
Step 2
The flour should turn a light cream color.
Step 3
Beat the eggs on low speed with a mixer.
Step 4
Without stopping the mixing, gradually add the toasted flour to the eggs and beat until fully combined. Bring the milk to a boil. Add sugar to it and stir until the sugar crystals dissolve completely. Once the milk boils, remove it from the heat and let it cool slightly - it should be warm before being poured into the egg mixture.
Step 5
Slowly pour the warm milk into the egg mixture while constantly stirring. Then place the egg-milk mixture over a double boiler and stir constantly until it thickens. It should not boil. Remove from heat and let it cool to warm. Then beat the mixture with a mixer together with the butter until fluffy. Finally, add vanilla sugar. The cream is ready.
