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

What each ingredient does

Large peas
Form the body of the soup once cooked, pounded and pressed into a smooth purée.
Butter
Adds richness and fat, carrying flavour and giving the softened vegetables a silky texture.
Cucumbers
Contribute moisture and a mild, fresh flavour as they soften in the butter.
Lettuces
Soften when sautéed, adding body and a gentle, green vegetable flavour.
Onions
Add savoury depth and aroma as they cook soft in the butter.

The step that matters

Press the soup through a fine sieve. Pressing the pounded peas through a fine sieve removes the fibrous skins and lumps, so the soup ends up smooth rather than grainy.

Swap the onion

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

  1. Beetrootfits better
  2. Cauliflowerfits better
  3. Chivefits better
  4. Onionthe original

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