To make your own Fyre Tonic you will need the following:
Apple Cider Vinegar
(you can also add fresh horseradish to this recipe but I had a difficult time sourcing any in our area)
Chop up a strong onion and fill a 500ml mason jar half way
3-4 garlic cloves, peeled and chopped
5 good chunks ginger, sliced off root
dash of cayenne pepper
Pour your homemade apple cider vinegar over all of the ingredients.
Allow to sit at room temperature for 4-6 weeks. At this point strain the tonic and compost the onion mixture. Add to taste (2 tablespoons to 1/4 cup) honey to liquid and shake jar until well dissolved. Take one spoonful daily.
