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

What each ingredient does

Vegetable marrow or cucumber
Forms the body of the dish, cooking down to a soft, tender texture.
Butter
Adds richness and fat to the sauce, carrying flavour.
Flour
Thickens the sauce as it boils with the cooking water.

The step that matters

Add the vegetable and cook until tender, about 15 minutes. Do not overboil.. Overcooking breaks down the vegetable's cell walls too far, leaving it mushy and watery. Stopping once it is tender keeps its texture and shape intact.

Swap the cucumber

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

  1. Shallotfits better
  2. Leekfits better
  3. Arrowrootfits better
  4. Cucumberthe original

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