Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried split green peas
- Break down during simmering to give the soup its body and thickness.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the pureed soup.
- Prepared hot mustard
- Adds a sharp, pungent note that balances the sweetness of the peas.
- Whipping cream
- Adds fat and creaminess to each bowl as it is served.
The step that matters
Simmering until tender. Dried split peas must cook long enough for their starch to fully soften; undercooked peas leave the puree grainy and thin, while steady gentle simmering prevents scorching on the bottom of the pot.

Fit is the average pairing score against peas, butter, pepper, cream. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
