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, moisture and bright acidity of the soup.
- Tofu
- Blends into a smooth, creamy texture that thickens the soup without dairy.
- Onion
- Softens and turns sweet and aromatic as it cooks until clear.
- Olive oil
- Carries fat-soluble flavors and helps soften the onion and tomatoes.
- Condensed tomato soup
- Adds concentrated tomato flavor and extra body to the base.
The step that matters
Warm through and add water as needed. Gentle heat keeps the blended tofu smooth and helps prevent scorching on the bottom of the pot. Adding water adjusts thickness so the soup stays pourable and evenly textured.
Swap the onion
How well each one fits the dish's main ingredients (tomato, olive, tofu, pepper):
- Capsicumfits better
