Why it works: Anchovy and ketchup match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 479 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Lobster Sauce
Ingredients
Directions
Prepare the lobster
Remove the spawn from the lobster.
Bruise the spawn finely in a mortar with a little butter.
Extract the meat from the claws and tail.
Cut the meat into small square pieces.
Make the sauce
Combine the spawn, lobster meat, anchovy liquor, ketchup, mace, horseradish, lemon half, gravy, and flour (mixed with a little butter) in a saucepan.
Melt the remaining butter and add it to the mixture.
Gently boil the mixture for 6-7 minutes.
Remove the horseradish, mace, and lemon from the sauce.
Squeeze the lemon juice into the sauce and simmer briefly.
Serve the sauce in boats.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lobster
- Provides the main meat and spawn, giving the sauce its flavour and body.
- Butter
- Adds richness and fat, carrying flavour and giving the sauce a smooth mouthfeel.
- Flour
- Thickens the sauce as it heats, giving it body.
- Lemon
- Adds acidity that brightens the rich flavours of the sauce.
- Gravy
- Adds savoury depth and moisture to the sauce.
The step that matters
Gently boil the mixture for 6-7 minutes. Flour thickens only as its starch swells in simmering liquid. Boiling too hard can break the butter emulsion and toughen the delicate lobster meat, so keep the heat gentle.
Swap the mace
How well each one fits the dish's main ingredients (lobster, butter, anchovy, ketchup, horseradish, lemon, flour):
- Capersfits better
- Parsleyfits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against lobster, butter, anchovy, ketchup, horseradish, lemon, flour. Candidates are from the same food group and used in at least 100 recipes.
