Start by thoroughly washing the fresh dill seeds and patting them dry. In a clean, dry glass jar or container, combine the dill seeds with salt and dried dill if using. Seal the container tightly and store in a cool, dark place. Every few days, gently shake or turn the jar to evenly distribute the seeds and salt. After 2-3 weeks of fermentation or curing, the dill will develop a strong aroma and flavor. Once complete, transfer the homemade dill to a clean jar for storage, keeping it in the refrigerator. Use as a fresh seasoning in your favorite dishes or as a condiment.
