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.
- New milk
- Forms the creamy base that gives the bisque its smooth, rich body.
- Cornstarch
- Thickens the milk as it heats, giving the bisque a smooth, velvety texture.
- Baking soda
- Neutralises some of the tomato acidity, softening the sharp tang.
- Butter
- Adds fat for richness and a smoother mouthfeel.
The step that matters
Combine the boiling milk with the tomatoes. Acidic tomatoes can curdle hot milk when they meet, so the milk and tomatoes should be combined carefully and served right away. Baking soda is added to the tomatoes first to reduce acidity and help prevent this.
Swap the tomato
How well each one fits the dish's main ingredients (milk, butter, egg, pepper, cream):
- Potatofits better
- Capsicumfits better
- Asparagusfits better
- Tomatothe original
Fit is the average pairing score against milk, butter, egg, pepper, cream. Candidates are from the same food group and used in at least 100 recipes.
