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

What each ingredient does

Butter
Melts to form the fatty base that carries the cheese and seasonings.
Cheese
Melts into the sauce to give it a rich, creamy texture and savory flavor.
Vinegar
Adds acidity that sharpens the flavor and balances the richness of butter and cheese.
Mustard
Adds sharp pungency and helps emulsify the melted butter and cheese.
Anchovy sauce
Contributes deep savory, umami flavor to the topping.

The step that matters

Stir until the cheese is fully dissolved. Cheese held over heat can turn grainy or oily if it overheats or separates. Keeping the heat low and stirring steadily lets the proteins melt smoothly into the butter and liquids.
