What are spirited vinegars? They are vinegars infused with herbs, spices, flowers or fruits. You can read more about spirited vinegars from Mountain Rose Herbs.
Chef Gaby introduced them to me. You can use them a few different ways. The most common is marinades and salad dressings. In this photo are L-R, Rosemary Vinegar, Coriander/Tarragon Vinegar, and Dill Vinegar. They need to infuse for at least 2 weeks.
