Onion and sauce barely smell alike, yet cooks put them together in 10,474 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Large onions
Provide a soft, sweet layer that contrasts with the earthy beetroot.
Beetroot
Forms the main structure of the salad and adds earthy sweetness and colour.
Italian sauce
Adds moisture and seasoning that soaks into the layered vegetables.

The step that matters

Boil the onions until well done. Onions that are not fully softened stay sharp and firm, which clashes with the tender beetroot. Cooking them thoroughly breaks down their cell structure so they become mild and sliceable.

Swap the beetroot

How well each one fits the dish's main ingredients (onion, sauce):

  1. Horseradishfits better
  2. Mustardfits better
  3. Chivefits better
  4. Beetrootthe original

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