Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the meaty body and substance that make the soup filling.
- Milk
- Forms the creamy base of the soup and adds richness and mild sweetness.
- Butter
- Adds fat and richness, and the flour coating helps thicken the soup as it heats.
- Wine
- Adds acidity and depth of flavour to the soup.
- Mustard
- Contributes sharp, pungent flavour that balances the richness of the milk and butter.
The step that matters
Stirring while the soup cooks. Milk can scorch or form a skin on the bottom of the pan over medium heat. Stirring keeps the milk proteins and flour evenly dispersed, prevents sticking, and helps the butter-flour mixture thicken the soup smoothly.
