This fiery, golden tonic is a powerhouse of bold, warming flavors — sharp horseradish, spicy ginger, earthy turmeric, bright citrus, and a slow-building heat from cayenne, all mellowed at the end with a swirl of raw honey. It's the kind of thing that wakes you up from the inside out, and once you've made a batch, you'll wonder how you ever went without it. For anyone navigating iodine restrictions, this recipe is a natural fit — every ingredient is a whole, unprocessed plant or spice, with no seafood, dairy, or iodized salt anywhere in sight. The two-week steeping process does the heavy lifting, drawing out the full depth of each ingredient into the apple cider vinegar base so the finished tonic is complex, layered, and genuinely satisfying. A daily shot straight from the jar is the classic approach, but it's also excellent stirred into warm water or drizzled over roasted vegetables. The batch keeps for up to six months in the fridge, so one round of prep pays off for a long time. It's low-effort, high-reward, and completely built from ingredients you can feel good about.

Add the grated horseradish, grated ginger, grated turmeric, sliced garlic, lemon zest and juice, orange zest and juice, crushed black peppercorns, and cayenne to a clean 1-quart wide-mouth glass jar. Tuck in the rosemary sprig, if using.
Pour the apple cider vinegar over the solids, pressing them down gently so everything is submerged. The jar should be nearly full; if the solids are not covered, add a splash more vinegar.
