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

What each ingredient does

Cracker crumbs
Provide the bulk and dry base that gives the balls their body.
Walnut meats
Add richness and a firm, nutty texture to the balls.
Hard-boiled egg yolks
Add fat and creaminess that help hold the mixture together.
Sweet milk
Adds moisture so the crumbs hydrate and the mixture binds.

The step that matters

Adding the sweet milk. Crumbs absorb liquid unevenly, so adding milk gradually until the mixture just holds together prevents balls that are either crumbly or soggy. Too much milk makes them fall apart in the soup.

Swap the walnut

How well each one fits the dish's main ingredients (meat, egg, milk):

Fit is the average pairing score against meat, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
