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

What each ingredient does

Pea shells
Simmered in water to release flavour and body into the stock.
Green peas
Cooked until tender, adding sweetness and a thick, smooth body to the soup.
Cucumbers
Add a cool, fresh flavour and some moisture to the soup.
Lettuces
Add mild, vegetal flavour and body as they cook down in the broth.
Onion
Adds savoury depth and aroma to the base of the soup.

The step that matters

Strain through a fine sieve. Pressing the cooked solids through a fine sieve removes fibrous pieces and skins, giving the soup a smooth texture rather than a grainy or stringy one.

Swap the onion
