Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh shelled peas
- Provide the main green flavor and starch that gives the soup its body.
- Milk
- Adds creamy body and mild sweetness to the soup.
- Butter
- Adds fat for richness and a smoother mouthfeel.
- Cream
- Adds richness and a silky texture when stirred in at the end.
The step that matters
Cooking the peas for 2 hours. Long, gentle heat softens the pea cell walls fully, so the peas break down and pass through the sieve smoothly. Undercooked peas leave a grainy, fibrous soup.
Swap the peas
How well each one fits the dish's main ingredients (milk, butter, pepper, cream):
- Almondfits better
- Walnutfits better
- Cocoafits better
- Peasthe original
Fit is the average pairing score against milk, butter, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
