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 Catsup
Ingredients
Directions
Prepare the mushrooms
Wipe the mushrooms clean and crush them with your hands.
Add a handful of coarse sea salt for every peck of mushrooms and let them stand overnight.
Extract and season the liquid
Strain the mixture through a sieve and press out all the juice.
For every gallon of liquid, add 1 ounce each of cloves, Jamaica ginger, and black pepper, along with ½ pound of coarse sea salt.
Reduce and bottle
Set the mixture on a slow fire and boil until half the liquid is reduced.
Once cooled, transfer to an earthen vessel and bottle it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Full grown mushrooms
- Supply the main juice that becomes the body of the ketchup.
- Coarse sea salt
- Draws moisture out of the mushrooms and helps preserve the liquid.
- Cloves
- Add a warm, pungent aroma to the liquid.
- Jamaica ginger
- Adds a sharp, warm aroma and spice to the liquid.
- Black pepper
- Adds sharp heat and a savoury bite to the liquid.
The step that matters
Boil down to half the liquid. Reducing the liquid concentrates its flavour and thickens it. A slow fire lets it reduce evenly without scorching on the bottom of the pan.
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.
