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 cloth and salt.
Place the mushrooms in a jar and add salt, ginger, whole pepper, mace, hay leaf, lemon rind, and sherry.
Heat and steep
Cover the jar tightly and heat it on the stove until it is thoroughly heated and just about to boil.
Let it sit for one or two days until the mushrooms absorb the spices.
Pickle and cool
Cover the mushrooms with hot vinegar, close the jar again, and heat until it just comes to a boil.
Remove from heat and let it cool completely.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Form the body of the pickle and absorb the spiced liquid as they steep.
- Sherry
- Adds a fortified wine aroma and mild sweetness to the spiced liquid.
- Hot vinegar
- Provides the sharp acidity that preserves and flavours the mushrooms.
- Ginger
- Adds warm, pungent aroma that infuses into the mushrooms.
The step that matters
Heating the jar before the vinegar is added. Heating only until just about to boil, rather than boiling hard, helps the mushrooms take up the spices without turning soft and rubbery. Overheating can break down their texture.
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.
