Why it works: Egg and bread are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 22,662 recipes. Both carry (e)-2-octenal, which smells fatty, green. The science ↓
Marrowball Soup
Ingredients
Directions
Make the marrowball mixture
Melt the piece of marrow slowly until slightly cooled.
Add the grated bread crumbs, egg yolk, salt, nutmeg, and mix well with a little cold water.
Cook the marrowballs
Take a teaspoonful of the mixture and drop it into boiling stock without covering the kettle.
If the ball falls apart, add more bread crumbs.
Let the balls boil slowly for three minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Marrow
- Adds richness and fat, giving the balls a moist, savoury body.
- Bread crumbs
- Absorb moisture and bind the mixture so the balls hold their shape.
- Egg yolk
- Binds the mixture and helps the balls set when heated.
The step that matters
Dropping the balls into boiling stock. If the mixture is too wet, the balls fall apart in the stock. Adding more bread crumbs firms the mixture so each ball holds together while it cooks.
