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
Ingredients
Directions
Prepare the tomatoes
Bring the tomatoes to a boil in a saucepan.
Add the baking soda and boil for 10 minutes, stirring occasionally.
Strain the tomato mixture through a fine sieve to remove the seeds.
Make the white sauce
Heat the milk in a double boiler.
Cream the butter in a bowl.
Mix the flour with the creamed butter.
Stir in 1 cup of the hot milk until smooth.
When the remaining milk boils, slowly pour in the flour mixture while stirring until it thickens, about 5 minutes.
Combine and serve
Add the strained tomato, salt, and pepper, and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body, acidity and flavor of the bisque.
- Milk
- Forms the creamy liquid base that gives the bisque its smooth, rich body.
- Flour
- Thickens the milk into a smooth sauce as its starch gelatinizes with heat.
- Butter
- Adds fat and richness, and helps the flour blend smoothly into the sauce.
- Baking soda
- Neutralizes some of the tomato's acidity, softening its sharp taste and reducing curdling risk.
The step that matters
Slowly pour the flour mixture into the boiling milk. Adding the flour mixture slowly while stirring keeps the starch dispersed so it thickens smoothly. Dumping it in can create lumps that are hard to smooth out. Stirring also keeps the milk from scorching on the bottom of the pan.
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.
