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 ↓
Mushroom Gravy
Ingredients
Directions
Salt and rest
Layer mushrooms in a deep earthen pan, sprinkling each layer with coarse sea salt.
Let them sit for 2-3 hours until softened.
Mash the mushrooms well and stir daily for 2 days.
Jar and boil
Pour into a stone jar, adding 1 ounce of whole black pepper for each quart.
Seal the jar and place it in a pot of boiling water, boiling for at least 2 hours.
Strain
Strain the juice through a fine sieve without squeezing the mushrooms.

What each ingredient does
- Full grown mushrooms
- Provide the main body and the savoury juice that becomes the gravy.
- Coarse sea salt
- Draws moisture out of the mushrooms and helps preserve them during the rest.
- Whole black pepper
- Adds a sharp, pungent aroma and flavour to the finished liquid.
The step that matters
Keeping the jar sealed and boiling. If the jar is not sealed or the water stops boiling, steam and heat escape unevenly and the mushrooms may not cook through or stay safe. Sustained, even heat for the full time is what drives the juice out and cooks the mixture thoroughly.
