Why it works: Mushroom and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 13,580 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Mushrooms
Ingredients
Directions
Prepare
Rub the mushrooms with a bit of flannel and coarse sea salt.
Remove the red inside from the larger mushrooms.
Sprinkle a little salt over the mushrooms.
Cook
Place the mushrooms in a stew-pan with mace and pepper.
Shake the pan as the liquid comes out.
Keep over gentle heat until the liquid is absorbed.
Pickle and store
Add enough vinegar to cover the mushrooms.
Warm the mixture.
Transfer everything to a glass or stone jar.

Mace and pepper barely smell alike, yet cooks put them together in 12,257 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mushrooms
- Main ingredient that softens and releases liquid during gentle cooking, then takes up the vinegar.
- Vinegar
- Provides the acidity that preserves and sharpens the pickled mushrooms.
- Mace
- Adds a warm, aromatic spice flavour to the mushrooms.
The step that matters
Keep over gentle heat until the liquid is absorbed. Gentle heat lets the mushrooms release their liquid slowly and then reabsorb it without scorching or toughening. High heat can burn the pan and make the mushrooms rubbery.
Swap the mace
How well each one fits the dish's main ingredients (mushroom, pepper, vinegar):
- Thymefits better
- Tarragonfits better
- Garlicfits better
- Macethe original
Fit is the average pairing score against mushroom, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
