Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sliced cheese
- Melts into the sauce, giving it body, richness and its main savoury flavour.
- Milk
- Provides the liquid that lets the cheese melt smoothly into a pourable sauce.
- Eggs
- Thicken the sauce as their proteins set, giving it a smooth, custard-like texture.
The step that matters
Incorporate the eggs over gentle heat. Egg proteins set at fairly low temperatures. Over the gentle heat of a double boiler they thicken the sauce smoothly, while high heat would scramble them and make the mixture grainy.
