Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Tomato
Provides the main flavour and body of the soup.
Baking soda
Neutralises tomato acidity, mellowing the taste and softening the colour.
Butter and flour
Flour thickens the milk and cream into a smooth, body-rich base with the butter.
Cream
Adds richness, fat and a smooth, velvety texture.
Milk
Thins the base and adds mild sweetness and body alongside the cream.

The step that matters

Adding the cream and milk to the butter-flour mixture. Adding liquid gradually while stirring constantly keeps the flour dispersed, so the sauce thickens smoothly without lumps.
