Vanilla Sauce

Ingredients

Directions

Make the base

  1. Combine butter, water, and sugar in a saucepan.

  2. Boil the mixture.

Temper the eggs

  1. Remove from heat and gradually pour the hot mixture into the beaten eggs, stirring constantly.

Thicken and finish

  1. Return the mixture to low heat and stir until thickened, preferably in a bowl set over boiling water to prevent curdling.

  2. Add the vanilla extract, then serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Thicken the sauce as their proteins set with gentle heat, giving it body.
Butter
Adds fat that makes the sauce rich and smooth on the palate.
Sugar
Adds sweetness and helps balance the richness of the eggs and butter.
Vanilla extract
Adds aromatic flavor that rounds out the sweetness.

The step that matters

Tempering the eggs. Pouring the hot mixture into the eggs slowly while stirring constantly warms the eggs gradually. If heat is added too fast, the egg proteins set in lumps and the sauce curdles instead of thickening smoothly.
