Someone gave me some "water kefir" grains and I've started fermenting with them. I used:
3 cups water
1/4 cup sugar (organic evaporated cane juice)
half an organic lemon
2 tiny dried figs
A little less than 1/4 cup dried "grains" (culture/starter)
Sliced fresh ginger
I did this in a large mason jar, started it yesterday afternoon. I'll check on it today, it's supposed to ferment in 24-72 hours.
The finished product the other person had made was delicious. Fermented and fizzy, and I could taste the lactobacilli. I love probiotics.
I'll keep you posted.
