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

What each ingredient does

American cream cheese
Melts into a smooth, creamy base that gives the rarebit its body.
Ale or beer
Thins the melting cheese into a pourable sauce and adds a malty flavour.
Dry mustard
Adds a sharp, pungent note that cuts the richness of the cheese.

The step that matters

Melting the cheese gently with the liquid. Cheese proteins tighten and turn grainy or oily when overheated, so the cheese should melt slowly while the ale is added gradually to keep the sauce smooth.

Swap the mustard

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

  1. Chivefits about as well
