Why it works: Onion and peanut oil work together. They rank in the top 8% of all ingredient pairs, and 540 recipes mention both. Both carry acetic acid, which smells sour, vinegar. The science ↓
The recipe
Ingredients
Contains: peanut (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Make the base
Saute the onions in oil until just translucent.
Stir in the cayenne and ginger.
Add the carrots and saute a couple more minutes.
Mix in the potatoes and stock.
Bring the soup to a boil and then simmer for about 15 minutes until the vegetables are tender.
Blend and finish
In a blender or food processor, puree the vegetables with the cooking liquid and the tomato juice.
Return the puree to the soup pot.
Stir in the peanut butter until smooth.
Taste the soup. If it is not naturally sweet, add just a little sugar to enhance the other flavors.
Reheat the soup gently, using a heat diffuser if needed to prevent scorching.
Add more water, stock, or tomato juice for a thinner soup.
Serve
Serve topped with plenty of chopped scallions or chives.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Break down into a thick, starchy body that gives the soup its smooth texture when pureed.
- Peanut butter
- Adds richness and body, thickening the soup and giving it its nutty flavor.
- Onions
- Build a sweet, savory aromatic base as they soften in oil.
- Carrots
- Add natural sweetness and color while contributing body to the puree.
- Tomato juice
- Adds acidity and liquid that balances the richness of the peanut butter.
The step that matters
Stir in the peanut butter until smooth. Peanut butter can clump or stay grainy if added to very hot liquid all at once. Stirring it in gradually, with the soup off a hard boil, helps it disperse evenly into a smooth, velvety texture.

Fit is the average pairing score against onion, peanut oil, carrot, potato, tomato, peanut, butter. 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).
