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

What each ingredient does

Brown flour
Thickens the broth so it has body and a smooth, rich texture.
Onions
Add sweetness and savory depth as they cook down into the broth.
Eggs
Hard-boiled whites and yolks add texture and richness to the finished soup.
Calf's head
Gives the broth its gelatin, body and meaty flavor as it simmers.

The step that matters

Adding the brown flour to the broth. Flour added to hot liquid clumps unless it is well whisked or mixed with a little cold liquid first. Smooth incorporation gives an even, velvety thickness.

Swap the onion
