Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Marrow Balls
Ingredients
Directions
Prepare

Cook until the balls rise to the surface.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef marrow
- Adds richness and fat that keeps the small balls moist as they cook.
- Egg white
- Binds the crumbs and marrow so the balls hold their shape in liquid.
- Bread crumbs
- Absorb moisture and add bulk, giving the balls a tender texture.
The step that matters
Drop the balls into simmering soup. Dropping them into a rolling boil can break them apart. A gentle simmer lets the egg white set slowly so the balls cook through and keep their shape.
