Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Green Pea Soup
Ingredients
Directions
Prepare and cook
Rinse the green peas through a colander to remove skins.
Add the milk to the peas and heat until boiling.
Thicken and finish
If the soup is too thin, thicken it with a little flour mixed with cold milk.
Season with salt and stir in the cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peas
- Provide the main body and flavour of the soup.
- Milk
- Adds liquid and creaminess, helping the soup become smooth when heated.
- Flour
- Thickens the soup by swelling with liquid as it heats.
- Cream
- Adds richness and a smoother, silkier mouthfeel.
The step that matters
Thickening with flour. Flour must be mixed with cold milk first so it disperses evenly, then stirred in; otherwise it forms lumps. Starch thickens the soup as it heats, so add it gradually and check consistency before adding more.
Swap the peas
How well each one fits the dish's main ingredients (milk, flour, cream):
- Almondfits better
- Pistachiofits better
- Chestnutfits better
- Peasthe original
Fit is the average pairing score against milk, flour, cream. Candidates are from the same food group and used in at least 100 recipes.
