Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peas
- Form the main body of the soup and give it its flavour and colour.
- Milk
- Adds creaminess and richness to the pureed soup.
- Butter
- Adds fat for a smoother, richer mouthfeel.
- Flour
- Thickens the soup as it is stirred in with the fat and liquid.
- Sugar
- Adds sweetness that balances the vegetable flavour.
The step that matters
Stir in the flour with the butter. Flour clumps if added to hot liquid without being well blended with fat first. Mixing it smoothly into the butter and then the milk and pea mixture gives an even, lump-free thickening.
Swap the peas
How well each one fits the dish's main ingredients (sugar, milk, butter, flour, pepper):
- Almondfits better
- Chestnutfits better
- Milletfits better
- Peasthe original
Fit is the average pairing score against sugar, milk, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
