Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cheese
- Melts into the sauce to provide the main rich, savory body of the dish.
- Egg
- Thickens the cheese mixture gently as it warms, giving it a smoother, more cohesive texture.
- Butter
- Adds fat and richness, helping the cheese melt smoothly into a glossy sauce.
- Sherry wine
- Adds acidity and aroma that balance the richness of the cheese.
The step that matters
Stir in the egg without beating it. Egg proteins set when heated, so gentle stirring over low warmth keeps the sauce smooth. Beating incorporates air and encourages overheating, which can scramble the egg and leave the sauce grainy.
