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, bay leaf, lemon rind, and sherry.
Cover the jar tightly and heat it on the stove until it is just about to boil.
Steep and pickle
Let it sit for one or two days until the mushrooms absorb the liquid and spices.
Cover the mushrooms with hot vinegar, seal the jar, and heat it again 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
- Small white button mushrooms
- The main ingredient, which softens and absorbs the pickling liquid and spices.
- Hot vinegar
- Provides the sharp acidity that preserves the mushrooms and gives the pickle its tang.
- Sherry
- Adds wine flavour and depth to the pickling liquid.
- Coarse sea salt
- Draws moisture out of the mushrooms and seasons them during the initial curing.
The step that matters
Heating the jar before the vinegar is added. Heating only until the liquid is just about to boil helps the mushrooms take up flavour without turning them mushy. Overheating breaks down their texture and can leave them soft and watery.
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.
