Mushroom Gravy
Ingredients
Directions
Salt the mushrooms
Layer mushrooms in a deep earthen pan, sprinkling each layer with coarse sea salt.
Let sit for 2-3 hours until the salt penetrates the mushrooms.
Mash the mushrooms well and let them sit for 2 days, stirring and mashing daily.
Cook and strain
Pour the mixture into a stone jar, adding 1 ounce of whole black pepper for each quart.
Seal the jar tightly and place it in a boiling water bath for at least 2 hours.
Strain the juice through a fine sieve into a clean saucepan.

What each ingredient does
- Full-grown mushrooms
- Provide the main body and flavour of the gravy as they break down into liquid.
- Coarse sea salt
- Draws moisture out of the mushrooms and helps break down their tissue over time.
- Whole black pepper
- Adds sharp, aromatic spice that flavours the gravy as it steeps.
The step that matters
Mashing and stirring the salted mushrooms daily. Salt draws water out of the mushrooms and breaks down their cell walls, so regular mashing exposes more surface to the salt and releases juice evenly. Skipping it can leave uneven breakdown and a weaker, unevenly seasoned liquid.
