Fire cider is a homemade tonic made by steeping various ingredients in apple cider vinegar. The mixture steeps for several weeks, during which the ingredients release their flavors and medicinal properties. The resulting liquid is a pungent, spicy and slightly sour elixir that helps boost the immune system and offers strong anti-inflammatory effects. $50.
