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

What each ingredient does

Bacon
Renders fat and flavour into the butter, giving the dish its savoury base.
Flour
Thickens the stock into a sauce as it cooks with the butter and bacon fat.
Stock
Liquid that cooks the potatoes and forms the body of the sauce.
Potatoes
Starchy pieces that soften in the stock and absorb its flavour.

The step that matters

Skim the mixture to remove foam. Foam rising from the boiling stock carries impurities that can cloud the sauce and taste bitter if left in, so it should be skimmed off while the potatoes cook.

Swap the potato

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

  1. Shallotfits better
  2. Chivefits about as well
  3. Capsicumfits about as well
  4. Potatothe original

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