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

What each ingredient does

Butter
Browns with the shallots and garlic, adding a rich, nutty flavour to the base.
Shallots
Soften and sweeten as they cook, giving the broth a mild, savoury onion flavour.
Mussels
Main ingredient; their shells open as they cook, releasing juices that form the broth.
Dry sherry
Adds acidity and aroma that brighten the broth and balance the richness of the butter.

The step that matters

Removing the mussels once the shells open. Mussels turn tough and rubbery when overcooked. Taking them off the heat as soon as they open keeps the meat tender and juicy.

Swap the garlic
