Why it works: Mushroom and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 13,580 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Husbboom Catsup
Ingredients
Directions
Salt the mushrooms
Cut the ends off the mushroom stalks and break them into a deep earthen pan.
Strew ¾ pound of salt among the mushrooms, reserving some for the top.
Let the mushrooms stand for 3 to 4 days, stirring gently once every 24 hours.
Drain off the liquid without pressing the mushrooms and strain it.
Make the catsup
Measure the liquid and boil it quickly in a clean stewpan until reduced by half.
For each quart of liquid, add ½ ounce of black pepper or ¼ teaspoon of cayenne and 1 drachm of mace.
Pour the catsup into a clean jug or jar, cover with a folded cloth, and keep in a cool place overnight.
Gently pour off the sediment and transfer the catsup into small bottles.
Bottle and store
Cork the bottles well and optionally add a teaspoon of salt oil to each before sealing to exclude air.
Store the bottles in a dry, cool place.

Pepper and mace barely smell alike, yet cooks put them together in 12,257 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
- Fresh mushrooms
- Form the bulk of the catsup, releasing the flavourful liquid that is strained and reduced.
- Coarse sea salt
- Draws liquid out of the mushrooms and preserves the mixture during the multi-day standing.
- Black pepper
- Adds pungent, warm spice flavour to the reduced liquid.
- Mace
- Adds a warm, aromatic spice note to the catsup.
The step that matters
Boil the liquid quickly until reduced by half. Reducing concentrates the flavour of the mushroom liquid and helps it keep. Boiling quickly limits the time the liquid spends at a simmer where it can darken or lose fresh flavour.
Swap the mace
How well each one fits the dish's main ingredients (mushroom, pepper):
- Thymefits better
- Marjoramfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against mushroom, pepper. Candidates are from the same food group and used in at least 100 recipes.
