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 its rich body and savoury flavour.
Olive oil
Adds fat that helps the sauce stay smooth and coat the palate.
Dry mustard
Contributes a sharp, pungent aroma that cuts the richness of the cheese.
Ale
Thins the melted cheese into a pourable sauce and adds malty flavour.

The step that matters

Keep the cheese melting gently. Cheese proteins toughen and separate when overheated, turning the sauce grainy and oily. Low, gentle heat keeps it smooth. Stir the ale in until fully combined so the sauce stays uniform.

Swap the mustard

How well each one fits the dish's main ingredients (cheese, olive, pepper):

  1. Capsicumfits better
  2. Tomatofits better
  3. Mustardthe original
  4. Spinachfits about as well

Fit is the average pairing score against cheese, olive, pepper. Candidates are from the same food group and used in at least 100 recipes.
