This is a technique for long-term mushroom preservation in your refrigerator. Mushrooms preserved using this method will last up to 2 years in cold-storage making this a fantastic way to process excess product.
• King oysters or black pearl oysters, diced
• Extra virgin olive oil
• Neutral oil (Canola)
• Pinch of salt
• Rosemary. 2 sprigs
• Chili flakes, a pinch
• 1 cinnamon stick
1. In a heavy-bottomed sauce pan heat up enough of a neutral flavored oil (such as canola) to cover the bottom of the pan.
2. Once the oil begins to smoke, add in diced mushrooms and a pinch of salt. Cook on high heat, stirring so that the mushrooms don't stick to the pan.
3. Cook until mushrooms shrink and start to turn a golden brown color.
4. When mushrooms are looking golden brown and delicious, remove them from the pan and let them cool to room temperature.
5. Transfer them to a sterilized/very clean jar or vessel. Cover the mushrooms entirely with extra virgin olive oil.
6. add rosemary, chili flakes, and cinnamon to the jar of mushrooms and oil.
The mushrooms, over time, will begin to plump up again and take on the flavor of the aromatics. If fully covered in oil, the mushrooms will last in a refrigerator for up to 2 years.
