Lemon and Liver Sauce

Ingredients

1 Lemon or Seville Orange
Liver (fresh, from poultry or rabbit)
2 tablespoons Butter
Optional: ½ cup Bacon (minced), juice of ½ Lemon, grated peel of Lemon, 1 teaspoon Tarragon or Chili Vinegar, 1 tablespoon White Wine, a pinch of Mace, Nutmeg, or Allspice, 1 Eschalot (pounded), a few leaves of Tarragon or Basil, Anchovy or Ketchup, Cayenne

Directions

Prepare the lemon

Remove the rind of the lemon or orange as thinly as possible, avoiding the white pith.
Cut off the white pith and slice the lemon into thin rounds, then remove the seeds.
Cut the slices into small squares and mince a little of the peel finely.

Make the sauce

Add the lemon squares and minced peel to the prepared liver in melted butter.
Warm the mixture together without boiling.

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

What each ingredient does

Lemon: Supplies the sharp acidity and fragrant oils that flavour the sauce.
Liver: Forms the body of the sauce, giving it richness and a soft texture.
Butter: Melts to carry flavour and add richness and a smooth, glossy mouthfeel.

The step that matters

Warm the mixture without boiling. Liver is delicate and can turn grainy, dry or curdled when it gets too hot. Gentle heat keeps the sauce smooth and the butter emulsified, while the lemon stays bright.

Swap the lemon
