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

What each ingredient does

Egg yolks: Bind the mixture so it holds together as a cohesive stuffing.
Bread crumbs: Absorb moisture and add body, giving the forcemeat a softer, spoonable texture.
Butter: Adds fat and richness, carrying flavour and keeping the stuffing moist.
Pounded chestnuts: Form the bulk of the forcemeat, providing starchy body and a mild, nutty sweetness.
