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

What each ingredient does

Liver
Forms the smooth base of the spread and supplies its rich, savoury flavour.
Butter
Adds fat for a smoother, creamier texture and richer mouthfeel.
Mustard
Adds sharp, pungent flavour that cuts the richness of the liver.
Anchovy sauce or mushroom catsup
Adds salty, umami depth that rounds out the liver flavour.

The step that matters

Mash the liver smooth on a hot water plate. Liver left with lumps or fibres gives a grainy spread. Mashing while it is still warm lets it break down more easily and blend evenly with the butter.

Swap the mustard
