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

What each ingredient does

Sardines
Provide the main savoury flavour and body of the sauce once chopped and simmered.
Butter
Adds richness and, when rubbed with flour, helps thicken the sauce.
Flour
Thickens the butter and liquid into a smoother, more cohesive sauce.
Lemon
Rind adds aromatic oils while the juice contributes brightness and acidity.
Shallot
Adds a mild aromatic onion flavour that mellows during simmering.

The step that matters

Adding the lemon juice and sardines after removing the rind and shallot. Boiling the sardines and lemon juice for too long can make the fish tough and the acidic juice taste harsh, so timing the final simmer matters. Removing the rind and shallot first keeps the sauce smooth and the flavours clean.
