Why it works: Clove and ginger match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,038 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Mushroom Catchup
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the mushrooms
Crush the mushrooms with your hands and sprinkle salt over them.
Let them stand overnight.
Place the mushrooms in a stewpan and set in a 400°F (200°C) oven for 12 hours.
Strain the mixture through a fine sieve.
Make the catsup
For every gallon of liquid, add 1 ounce each of cloves, Jamaica pepper, black pepper, and ginger, along with ½ pound of common salt.
Set on low heat and boil until half the liquid evaporates.
Transfer to a clean pot and let it cool before bottling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Full grown flaps of mushrooms
- Main body of the sauce, releasing liquid and flavour as it breaks down.
- Common salt
- Draws moisture out of the mushrooms and seasons the liquid for preservation.
- Cloves
- Adds warm, aromatic spice flavour to the liquid.
- Ginger
- Adds pungent, aromatic warmth to the liquid.
The step that matters
Boil until half the liquid evaporates. Reducing the liquid concentrates its flavour and salt. Boiling too gently or stopping early leaves a thin, weakly seasoned result, while over-reducing can make it overly salty and dark.
Swap the ginger
How well each one fits the dish's main ingredients (mushroom, clove, pepper):
- Thymefits better
- Allspicefits better
- Marjoramfits better
- Gingerthe original
Fit is the average pairing score against mushroom, clove, pepper. Candidates are from the same food group and used in at least 100 recipes.
