Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce
- Forms the edible wrapper that holds the filling while it simmers.
- Green peas
- Provide the main filling, adding bulk and a sweet, mild flavor.
- Flour
- Thickens the pea mixture slightly so it holds together in the lettuce.
- Onion
- Adds savory aroma and depth to the pea filling.
The step that matters
Tie each lettuce carefully. Lettuce leaves are delicate and wilt or tear when heated. A snug, even tie keeps the filling sealed inside during the long simmer, so it does not leak into the stock.
Swap the onion
How well each one fits the dish's main ingredients (lettuce, peas, flour):
- Beetrootfits better
- Shallotfits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against lettuce, peas, flour. Candidates are from the same food group and used in at least 100 recipes.
