Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, and beating it creates a creamy, smooth texture.
- Brown sugar
- Adds sweetness and a molasses-like caramel flavor, and helps keep the sauce moist.
- Egg yolk
- Emulsifies the butter and thickens the sauce when gently heated.
The step that matters
Simmer slowly while stirring constantly. Egg yolk thickens the sauce through gentle heat, but it can curdle or scramble if it overheats or sits unstirred on the heat. Slow, constant stirring keeps the heat even and the sauce smooth.
