Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Mushrooms
Ingredients
Directions
Prepare
Cut off the roots of the mushrooms and clean them with a flannel and salt.
In a jar, combine the mushrooms with salt, ginger, whole pepper, mace, bay leaf, lemon rind, and sherry.
Heat the jar on the stove until just boiling.
Let the mixture sit for 1–2 days to absorb the flavors.
Pickle and bottle
Cover the mushrooms with hot vinegar.
Bring the vinegar to a boil.
Once cooled, divide the mushrooms and spices into wide‑mouthed bottles.
Fill the bottles with the vinegar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Small white mushrooms
- Form the main body of the pickle and absorb the seasoned vinegar and sherry flavors.
- Sherry
- Adds aromatic sweetness and depth to the seasoned mushroom mixture.
- Hot vinegar
- Acidity that preserves the mushrooms and gives the pickle its sharp flavor.
- Ginger
- Contributes warm, aromatic spice that flavors the mushrooms during the resting period.
The step that matters
Covering the mushrooms with hot vinegar. The vinegar must be fully hot and the mushrooms fully covered so the acid penetrates evenly and the pickle keeps well. Uncovered mushrooms can spoil or darken at the surface.
Swap the mace
How well each one fits the dish's main ingredients (mushroom, ginger, pepper, lemon, sherry, vinegar):
- Thymefits better
- Marjoramfits better
- Peppermintfits better
- Macethe original
Fit is the average pairing score against mushroom, ginger, pepper, lemon, sherry, vinegar. Candidates are from the same food group and used in at least 100 recipes.
