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

What each ingredient does

Ground beef: Forms the main body of the meatballs and provides savory flavor and richness.
Eggs: Bind the meat mixture so the meatballs hold their shape while cooking.
Breadcrumbs: Absorb milk and keep the meatballs tender and moist rather than dense.
Flour: Thickens the pan drippings and broth into a smooth sauce.
Sour cream: Adds tangy richness and a creamy body to the finished sauce.
Butter: Adds fat for frying and a rich, savory flavor to the meatballs and sauce.

The step that matters

Cook the flour until the raw taste is gone. Flour thickens only when heated, and undercooked flour leaves a raw, pasty taste. Cooking it for about 5 minutes after adding the broth cooks out that flavor and lets the sauce thicken fully.
