Note: While black currant leaves and berries are generally safe, individuals with kidney stones, severe gastrointestinal conditions, or allergies should consult a healthcare provider before consuming large amounts.

To freeze blackcurrants (Ribes nigrum) properly for optimal preservation and ease of use later on, the best method is as follows:

Steps for Freezing Blackcurrants:

1. Wash and Sort: Rinse the berries gently under cold water to remove any dirt or debris. Sort out any damaged or unripe fruits.
2. Dry Thoroughly: Pat dry with paper towels or use a salad spinner to ensure no excess moisture remains, which can lead to freezer burn.
3. Freeze Individually:
- Spread the cleaned and dried berries in a single layer on a baking sheet lined with parchment paper.
- Place the tray in the freezer until the berries are completely frozen (usually about 2 - 4 hours).
- Once frozen solid, transfer them into an airtight container or freezer bag, removing as much air as possible before sealing.
4. Avoid Cluster Freezing: While freezing entire clusters might seem convenient, it often leads to clumping together during storage, making it difficult to separate later without damaging the fruit.
5. Label and Store: Label the containers with the date and contents. Before placing back in the freezer, press out any remaining air from bags to prevent ice crystal formation.
By following these steps, you will maintain the quality, texture, and flavor of your blackcurrants when defrosted for future use.
