Oyster mushroom freezing at home

The benefits of freezing

Among the methods for harvesting fungi at home, methods of freezing oyster mushrooms for the winter are among the most effective:

  • If you store frozen mushrooms in the refrigerator’s freezer at the right temperature, they retain their natural structure, integrity and color.
  • If you properly freeze oyster mushrooms in the freezer, they will retain the nutritional quality and natural smell.

Shelf life of frozen oyster mushrooms is 6 months for heat-treated and 12 months for fresh-frozen. At the same time, it is easy to track the expiration date if packets are marked with freeze dates. Optimum temperature condition - -18 ° С

Stored in ice cream, they act as a semi-finished product, convenient for the subsequent preparation of various culinary dishes. In contrast to pickling and canning, it is possible to prepare the product by freezing portionwise, which facilitates subsequent use, limited by the amount required for one meal. The percentage of useful substances and biological value contained is almost at the fresh level.

Freeze preparation

Sorted items are suitable for freezing in the freezer:

  • without yellow spots and mechanical damage on the mushroom hat,
  • fresh, without pungent odor,
  • not overgrown, young, with juicy white pulp, strong structure and blue-gray hat.

Overgrown mushrooms are not suitable for harvesting, because they have a fibrous structure and a fresh taste of mushroom pulp, which acquires hard-to-survive rubber in the process of preparation.

Mushroom age is easily determined by the size of the cap. In an overgrown specimen, its diameter reaches 15-30 cm.

The leg of these fungi contains the least amount of healthy substances, they are inferior in taste to mushroom pulp and are tough in structure, therefore they are not often used for freezing, but cut completely or leaving short stumps.

Before freezing, they are cleaned of excess debris by washing (but not soaking) in running water and subsequently carefully drying.

If there is no opportunity to freeze mushrooms at home on the day of their collection or purchase, they are stored in the refrigerator, without first cleaning and without washing, whole, not cut into pieces. This allows you to keep fresh.

Fans of fried oyster mushrooms for their subsequent use in pies, pancakes and pizza are suitable for freezing mushrooms after their preliminary frying. Fry them in vegetable or butter for 20 minutes. to complete evaporation of the fluid secreted by the mushrooms and the appearance of a golden crust. Cooled packages are portioned and laid for long-term storage in a refrigerator for frozen foods.
