Ferment Fungi into Meat-Believe Beef
Many years ago I developed a style of recipe that turns mushrooms into a meaty substitute. Here is one that brings on the unique flavors of corned beef to cremini mushrooms.
One Quart
INGREDIENTS: I use brown cremini mushrooms
- cremini – 2 LBS
- olive oil – 4 TBS, divided
- shallots – 1/4 cup, minced
- BRINE:
- black pepper – 1/4 tsp
- caraway seeds – 1 tsp, ground
- dill seed – 1 tsp
- paprika, sweet – 1 tsp
- soy sauce – 2 TBS
- sea salt – 2 tsp
- filtered water
- AFTER FERMENTATION: 2 TBS balsamic vinegar
INSTRUCTIONS:
- Preheat oven to 400º
- Clean mushrooms with a damp cloth
- Cut only larger mushrooms to make uniform
- Place on a baking sheet and spray or toss lightly with oil
- Bake for 30-40 minutes until shrunken and wrinkled; cool
- Slice mushrooms 1/4 inch thick
- Mince the shallots and toss with mushrooms
- Create the brine and toss the mushrooms
- Load a clean quart fermentor jar with the mushroom mixture, pressing down as you go until the mixture reaches a half inch from the jar lip
- Add filtered water to within a half inch from the jar lip
- Complete sealing the fermentor according maker’s instructions so the ingredients remain under the brine during fermentation
- Ferment at room temperature for 3 days, add the balsamic vinegar, then refrigerate

I serve by tossing corned creminis right out of the fridge into a hot vegetable stew, or soup, or fried rice to warm the mushrooms, but not destroy the live culture.
Of course, you could make a reuben sandwich!
