Fire cider is a preparation that has been made in American folk herbalism for decades, popularized by herbalist Rosemary Gladstar, though the tradition of strong, warming vinegar-based immune preparations goes back much further in various folk traditions. It is made from a combination of intensely warming, antimicrobial, and immune-supportive ingredients macerated in apple cider vinegar and finished with honey.
It is sharp, spicy, warming, and genuinely useful as a daily immune tonic through the autumn and winter months. It is also one of the most satisfying and customizable preparations in the home apothecary.
The Classic Recipe
The core ingredients: horseradish root (grated fresh, about a thumb-length piece, 3 to 4 tablespoons), fresh ginger (similarly grated, 3 tablespoons), onion (finely chopped, half a medium onion), garlic (finely minced, four to six large cloves), fresh hot pepper (one chili, finely sliced), and citrus zest (one lemon or orange, zested).
Optional additions for depth and additional immune support: a cinnamon stick, three or four cloves, a tablespoon of dried rosemary, a tablespoon of dried thyme, a teaspoon of turmeric powder and a few grinds of black pepper (for enhanced curcumin absorption), and a tablespoon of dried elderberries.
Pack all ingredients into a quart mason jar. Pour raw apple cider vinegar over everything until the jar is completely full and all plant material is submerged. Cap with a non-metal lid (or place parchment between the jar and a metal lid to prevent corrosion). Leave in a cool, dark place for four weeks, shaking every day or two. Strain through cheesecloth, pressing firmly, and combine with raw honey (about a quarter to a third cup honey per cup of strained liquid, adjusted to taste). Bottle and label.
How to Use It
One to two tablespoons daily as a tonic through the autumn and winter months. A tablespoon stirred into a glass of warm water with a squeeze of lemon as a morning shot. Increased to several doses daily at the onset of illness. It can also be used as a salad dressing base: fire cider combined with olive oil is an excellent immune-supportive dressing that adds genuine medicinal value to everyday food.
