We recommend using organic lemons for this. You can add spices to this before the fermenting process, such as peppercorns, dried chilies, coriander seeds, a cinnamon stick, etc. When ready to use, rinse under cold water and scrap out the pulp. The part you want to use is the lemon peel, which a little goes a long way. Dice up and put in salad dressing, marinades, soups, sauces, etc.
