I have been using fire cider for more than 5 years, especially during almost 2 years long pandemic.  Here is the recipe: http://www.mommypotamus.com/fire-cider-recipe/

Also, there are some notes as addition of our 2016 posting, http://www.jnlyman.com/blog/2016/04/15/fire-cider-home-made-natural-remedy/

* I did not use onion, lemon and rosemary which float on top of the vinegar and may create an issue of spoilage.  So I used more turmeric and ginger root.

* Since I did not use fermenting weight to hold down the veggies, I put hot peppers first, then garlic, turmeric and ginger to prevent light veggies floating.

* Shake once a day to prevent spoilage

Enjoy
