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 ↓
Mock Bisque Soup
Ingredients
Directions
Prepare the tomatoes
In a pot, stew the tomatoes.
Add the baking soda to the stewed tomatoes and stir well.
Strain the tomato mixture.
Make the milk base
In a double boiler, bring the milk to a boil, reserving ½ cup of milk to mix with the flour.
Mix the flour smoothly with the reserved cold milk, then add it to the boiling milk and cook for 10 minutes.
Add the butter, salt, and pepper to the milk.
Combine and serve
Combine the milk mixture with the strained tomatoes and serve immediately.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Canned tomatoes
- Provide the main body, acidity and flavor of the soup.
- Milk
- Forms the creamy base of the soup.
- Flour
- Thickens the milk so the soup has body.
- Butter
- Adds richness and a smooth mouthfeel.
- Baking soda
- Neutralizes some of the tomato acidity, softening its sharpness.
The step that matters
Adding the baking soda to the tomatoes. Baking soda reacts with acid in the tomatoes and releases carbon dioxide, which can foam the mixture. Stirring well and adding it before combining with the milk keeps the reaction even and reduces the risk of the milk curdling when the two are joined.
Swap the tomato
How well each one fits the dish's main ingredients (milk, flour, butter, pepper):
- Potatofits better
- Capsicumfits better
- Chivefits better
- Tomatothe original
Fit is the average pairing score against milk, flour, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
