Why it works: Mushroom and olive are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 4,571 recipes. Both carry trans,trans-2,4-nonadienal, which smells fatty, green. The science ↓
Mushrooms
Ingredients
Directions
Prepare the mushrooms
Put button mushrooms into a mixture of milk and water.
Wipe the mushrooms with a clean cloth.
Soak them in spring water and sprinkle with coarse sea salt.
Boil the mushrooms for four minutes, then drain immediately.
Cover the mushrooms between two cloths and dry them well.
Pickle and bottle
Boil distilled vinegar with mace and a little white pepper until cold.
Pour the cooled vinegar over the mushrooms.
Place mushrooms in small glass bottles with wide necks and pour a teaspoon of olive oil on top.
Cork the bottles tightly and tie leather around the corks.
Serve
To use, remove the oil with a cotton-tipped stick or the small end of a teaspoon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Button mushrooms
- Form the main body of the pickle, absorbing the vinegar flavour as they sit.
- Double distilled vinegar
- Acidity that preserves the mushrooms and gives the pickle its sharp flavour.
- Olive oil
- Forms a layer on top that seals the mushrooms from air in the bottle.
- Mace
- Adds a warm, aromatic spice flavour to the pickling vinegar.
The step that matters
Drying the mushrooms after boiling. Mushrooms that stay wet after draining dilute the pickling vinegar and can spoil sooner, so they should be dried well between cloths before adding vinegar.
Swap the white pepper
How well each one fits the dish's main ingredients (mushroom, milk, vinegar, mace, olive):
- Thymefits better
- Clovefits better
- Garlicfits better
- White pepperthe original
Fit is the average pairing score against mushroom, milk, vinegar, mace, olive. Candidates are from the same food group and used in at least 100 recipes.
