Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Strained stewed tomato
- Provides the main tomato flavor and body of the soup.
- Clear soup
- Forms the liquid base that the other ingredients are suspended in.
- Corn starch
- Thickens the soup as it heats, giving it a fuller texture.
- Butter
- Adds richness and a smooth mouthfeel to the finished soup.
- Sugar
- Balances the acidity of the tomato for a rounder flavor.
The step that matters
Stirring in the corn starch. Corn starch must be fully dispersed before heating, or it clumps. As it heats, its granules swell and gelatinize, which thickens the soup evenly.
