Thank you to Mike Quigley for contributing this recipe for homemade fizzy ginger drinks!
First I made the ginger bug liquid by adding about 30g of chopped ginger to along with and 1 Tbsp chopped ginger and 1 Tbsp of sugar per day. I based it on a youtube video (in the gallery), but 2 Tbsp of sugar per day was too much. I used regular ginger. Sometimes the inorganic stuff doesn’t have yeast on it, and so won’t work, but in my case it did. I might try looking for ginger at the farmers market.
For the lemonade, I used 1 can of frozen lemonade mixed with filtered water and 1/4 cup of ginger bug liquid (just pour it through a strainer to remove any solid pieces of ginger). Then I left it in Grolsch bottles in the cupboard until it was fizzy, opening the bottle once per day to check.
