- 450 grams mushrooms, blanched (about 500 grams fresh)
- 200 grams leftover sauerkraut brine (from fully fermented sauerkraut)*
- 130 grams vinegar (5% acidity)
- 1 tablespoon dried rosemary
- 1 tablespoon dried oregano
- 1 teaspoon dried basil
- Blanching mushrooms can change their density. So the fresh mushroom weight doesn’t always equal the blanched weight. I suggest starting with about 500 to 600 grams of fresh mushrooms.
- Optional: before you get started, place the fresh mushrooms in some direct sunlight for about 30 minutes to increase the Vitamin D levels!
- Wash mushrooms well in cool water, removing any dirt. Cut them into quarters or halves
- Add the mushrooms to a large bowl.
- Bring some water to a boil, enough to cover the mushrooms.
- Once your water is boiling, pour it over the mushrooms to blanch them. Leave them in the hot water for about three to five minutes.
- Strain off the water through a colander and let the mushrooms cool to room temperature.
- Pack the mushrooms and spices into a clean glass jar. Depending on the mushroom type and size, you may need to squeeze them and pack them into the jar to fit.
- Mix the sauerkraut brine and vinegar, then pour it over the mushrooms to cover, leaving some room to place your fermentation weight. (You may have some left over).
- Place a fermentation weight in the jar to keep the mushrooms submerged. Close the jar with a rust-proof lid.
- Allow the mushrooms to culture at room temperature for about 72 hours, then you can remove the fermentation weight and refrigerate. (You will notice the mushrooms contract and shrink up a bit in the acidic brine).
