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 flavour of the bisque.
- Milk
- Adds creaminess and a smooth, rich texture to the soup.
- Butter
- Adds fat for richness and a silky mouthfeel.
- Baking soda
- Neutralises some tomato acidity and helps keep the milk from curdling.
- Sugar
- Softens the sharpness of the tomatoes, adding balance and sweetness.
The step that matters
Adding the tomatoes to the milk. Acidic tomatoes can curdle hot milk. Baking soda is added to the tomatoes first to reduce acidity, and the milk should be reheated before combining so the mixture stays smooth.
Swap the onion
