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 and provides the main body and rich flavour.
- Eggs
- Thicken the sauce as they set gently with heat, giving it a smooth, custard-like body.
- Cream
- Adds moisture and richness, keeping the sauce smooth and easy to pour.
- Butter
- Adds fat and richness, helping the cheese melt smoothly.
- Baking soda
- Raises the pH of the cheese, helping it melt more smoothly and stay less stringy.
The step that matters
Stir the eggs and cream into the melted cheese. Eggs curdle if they get too hot or are added without constant stirring. Once the cheese is melted, keep the heat moderate and stir constantly so the eggs thicken the sauce evenly and it stays smooth.
Swap the mustard
How well each one fits the dish's main ingredients (cheese, butter, pepper, sauce, cream, egg):
