Why it works: Liver and anchovy work together. They rank in the top 5% of all ingredient pairs, and 197 recipes mention both. Both carry hexanol, which smells green, fruity. The science ↓
The recipe
Ingredients
Contains: milk, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
The book says “a very sharp oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the paste
Pound the cooked livers until smooth.
Mix in the mustard, salt, cayenne, anchovy essence, and butter to form a paste.
Rub the mixture through a sieve.
Bake and serve
Spread the paste on hot buttered toast.
Place in a 400°F (200°C) oven for 10 minutes to heat thoroughly.
Cut into convenient pieces.
Garnish with parsley.
Serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked chicken or turkey livers
- Provide the main body and rich flavor of the spread.
- Prepared mustard
- Adds sharp, tangy flavor that balances the richness of the liver.
- Anchovy essence
- Adds a savory, salty depth to the paste.
- Butter
- Adds fat that makes the paste smooth and spreadable.
The step that matters
Rubbing the mixture through a sieve. Pressing the paste through a sieve breaks down any remaining fibers and lumps, giving the smooth texture the dish depends on. Skipping or rushing this step leaves a grainy spread.

Fit is the average pairing score against liver, pepper, anchovy, butter, parsley. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
