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

What each ingredient does

French rolls
Their crumbs cook down into a pulp that thickens the milk into a sauce.
Butter
Adds richness and a smooth, glossy texture to the finished sauce.
Milk
Forms the liquid base that the bread crumbs thicken into a sauce.
Cream
Adds richness and body in the alternative version.
Grated horseradish
Provides the sharp, pungent flavour that defines the sauce.

The step that matters

Reducing the bread crumbs to a pulp. If the milk boils too hard or too long, it can scorch on the bottom of the pan, and the crumbs may not break down fully, leaving a lumpy or uneven texture. Stirring keeps the starch evenly dispersed as it thickens.

Swap the radish

How well each one fits the dish's main ingredients (milk, sugar, butter, cream, vinegar, mustard, horse):

  1. Radishthe original
  2. Horseradishfits about as well
  3. Potatofits less well
  4. Shallotfits less well

Fit is the average pairing score against milk, sugar, butter, cream, vinegar, mustard, horse. Candidates are from the same food group and used in at least 100 recipes.
