Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Minced cheese
- Melts into the sauce and provides the main body, richness, and savory flavor.
- Butter
- Adds fat that helps the cheese melt smoothly and evenly.
- Beer or ale
- Adds liquid that loosens the melted cheese into a smooth, spreadable sauce.
The step that matters
Gradually pour in the beer or ale while stirring until smooth. Adding the liquid slowly while stirring keeps the cheese emulsified. Pouring it in all at once or over high heat can make the cheese separate, turn stringy, or become grainy.
