Why it works: Onion and parsley are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 25,843 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young peas
- Form the main body of the dish and carry its bright green flavor.
- White sauce
- Adds body and creaminess, coating the peas as the dish simmers.
- Butter
- Contributes richness and a smooth, rounded mouthfeel.
- Sugar
- Adds a little sweetness that balances the savory butter and salt.
The step that matters
Adding the liaison. A thickener stirred into hot liquid can form lumps if it is not dispersed quickly. Stirring briskly as it goes in spreads it evenly, so the stew thickens smoothly instead of clumping.
Swap the peas
How well each one fits the dish's main ingredients (sauce, butter, sugar, onion, parsley):
- Chestnutfits better
- Sesamefits better
- Chickpeafits better
- Peasthe original
Fit is the average pairing score against sauce, butter, sugar, onion, parsley. Candidates are from the same food group and used in at least 100 recipes.
