How to preserve black currants
Unlike leaves, which can be harvested almost all year round, currant berries are harvested once, and only some varieties can yield twice a year. It is better to eat or process berries picked in the rain, because excess moisture leads to rapid deterioration of the product.
When the currants are harvested according to all the rules, then it can be stored:
- fresh in the refrigerator or frozen in the freezer;
- dry indoors;
- pureed with sugar (confiture);
- canned in jars for the winter.
An important fact! If the processing of berries is planned in the next two weeks, then at temperatures up to 12 ° C and average humidity, they will not have time to deteriorate. Therefore, it is better to keep them in the refrigerator at this time.
For competent freezing of black currants for a year in advance, it is important to observe the following cycle of actions:
- Buy or collect on your own the most selected fruits (large, without damage), rinse and dry.
- Spread out evenly in one layer; if you have to increase the number of layers, then make a plastic layer between them.
- The freezing process takes from 12 to 20 hours, and preferably all 24.
- Then pour the frozen berries into a plastic or paper bag and store in the freezer. The shelf life of such fruits is up to 12 months.
To dry the berries, it is necessary to sort out, wash and dry thoroughly, then lay them evenly in one layer. You can dry it in the air, in a special dryer for berries or in an oven preheated to 60-70 degrees for about 4 hours. Transfer the dried berries to an airtight jar or just a bag. Store only in a dry place at room temperature. This is an effective way to preserve vitamins and minerals, but it is still recommended to give preference to storage in the form of freezing, since some of the nutrients are irretrievably lost during drying.
