I got this recipe from my mother in law who originally got it from Trim Healthy Mama. I don't even know how close this recipe is to the original or how much we have adapted it. But, I do know that it's a go-to recipe every time we are beginning to feel the least bit under the weather. I will write my version below but feel free to adapt in any way that you like. Just don't add sugar because that will defeat the purpose of it.
You will need:
2 tbsp apple cider vinegar (with the mother)
3 tbsp lemon juice
2 cm piece of fresh ginger OR 1 tsp ground ginger
stevia to taste
If you are using fresh ginger (which I prefer over ground ginger), place ginger and 1 cup of water in high speed blender and blend until smooth. Place ginger water in a tall mason jar. Add lemon and apple cider vinegar to jar. Add water until jar is full. Sweeten with stevia to taste. I use Trim Healthy Mama stevia (ordered online) and it is so pure that a little goes a long way. I like to add a drop or two of doTERRA's grapefruit essential oil or wild orange essential oil for added immune support benefits. Enjoy!
