Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peanuts
- Ground peanuts give the soup body and a rich, nutty flavour as they cook into the milk.
- Rich milk
- Forms the liquid base and carries the peanut flavour through the soup.
- Heavy cream
- Adds richness and a smooth, silky mouthfeel when stirred in at the end.
The step that matters
Adding the heavy cream just before serving. Cream is added off the heat near the end so it stays fresh-tasting and smooth. Boiling it for long can cause it to separate or taste flat, and fat-rich dairy thickens and dulls as it reduces.
Swap the peanut
How well each one fits the dish's main ingredients (milk, pepper, cream):

Fit is the average pairing score against milk, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
