Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Slowly softened onions give the soup its sweetness and main body.
- Margarine
- Fat that carries the onions' cooking and helps them brown gently.
- Flour
- Thickens the soup so it has body rather than being watery.
- Mozzarella cheese
- Melts over the top to form a stretchy, browned crust.
The step that matters
Saute the onions until clear. Onions cooked too quickly can scorch before they soften, leaving bitter flavor. Cooking them gently until translucent builds the soup's sweetness and depth.
Swap the onion
