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

What each ingredient does

Black beans
Form the body of the soup and thicken it as they break down when pressed.
Cold butter
Adds richness and a silky texture when stirred into the hot soup.
Hard-boiled egg yolks
Add a crumbly, rich texture and mild flavour to the finished soup.
White wine
Adds acidity and aroma that brighten the heavy bean base.
Lemon
Adds sharp acidity that balances the earthy beans and richness.

The step that matters

Adding the cold butter off the heat. Cold butter stirred into hot soup emulsifies into a smooth, glossy texture; if the soup boils hard after it goes in, the butter can separate and leave the soup greasy.

Swap the beans
