Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the creamy body of the soup once heated and thickened.
- Cornstarch
- Thickens the hot milk into a smooth, lightly bodied sauce.
- Butter
- Adds richness and smoothness to the thickened milk.
- Tomatoes
- Provide the tomato flavour and acidity that gives the bisque its character.
- Baking soda
- Neutralises some tomato acidity, softening its sharpness and keeping the milk from curdling.
The step that matters
Scald the milk and thicken it gently. Tomato acid can curdle hot milk, so the milk should be heated gently and kept below a hard boil. Cornstarch must be stirred in smoothly so it thickens evenly without lumps.
Swap the tomato
How well each one fits the dish's main ingredients (milk, butter, pepper):
- Potatofits better
- Capsicumfits better
- Tomatothe original
- Asparagusfits about as well
Fit is the average pairing score against milk, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
