Add water to the cup or jar and stir it around with a spoon. The water will help separate the seeds from the pulp.3. Let the mixture sit for 1-2 days until a mold layer starts to form on top of the water. This is a good sign that the fermentation process is happening, which helps to break down the gel-like substance surrounding the seeds.4. Once the mold layer has formed, scoop it off with a spoon, then pour the contents of the cup or jar through a fine-mesh sieve to separate the seeds from the remaining pulp.5.

Once the seeds are dry, store them in a labeled envelope or container in a cool, dry, and dark place until the next planting season.
