Why it works: Horseradish and lemon match in chemistry and in kitchens. They rank in the top 9% of all ingredient pairs, and cooks put them together in 1,155 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Lobster Sauce
Ingredients
Directions
Prepare the lobster
Remove the spawn from the lobster.
Bruise the spawn in a mortar with a little batter.
Take all the meat from the claws and tail, and cut it into small square pieces.
Make the sauce
In a saucepan, combine the spawn, lobster meat, ketchup, mace, horseradish, lemon juice, and gravy.
Melt the butter.
Mix the melted butter with flour to thicken the sauce.
Gently boil the mixture for 6-7 minutes.
Remove the horseradish, mace, and lemon pieces.
Squeeze the lemon juice into the sauce.
Simmer briefly.
Serve.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lobster
- Provides the main meaty texture and the sweet, rich flavour of the sauce.
- Butter
- Adds richness and fat, carrying flavour and giving the sauce a smooth mouthfeel.
- Flour
- Thickens the sauce as it heats, giving it body rather than a thin liquid.
- Gravy
- Supplies savoury body and depth to the liquid base of the sauce.
- Lemon
- Adds acidity that brightens the rich flavours of the lobster and butter.
The step that matters
Mixing the melted butter with flour. Flour must be fully blended into the butter and liquid so it hydrates evenly; stirring it in unevenly leaves lumps and an uneven, floury thickness.
Swap the mace
How well each one fits the dish's main ingredients (lobster, ketchup, horseradish, lemon, butter, flour):
- Capersfits better
- Tarragonfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against lobster, ketchup, horseradish, lemon, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
