make your own ginger beer! it’s much better than shop bought rubbish and only contains natural ingredients. plus you also learn how fermentation works. here’s the recipe:
add one cup of sugar to a clean 2 two litre plastic pop bottle. finely grate about 2 tablespoons of root ginger and add this to the bottle. juice a lemon and add that. now add about 1/4 teaspoon of baking yeast. fill to about three quarters with cold water. shake until the sugar is dissolved then top up with water to about 4cm from the top and screw the lid on as tight as you can. leave in a warm place (about 30-35°C) for 24 hours. DANGER! any longer and you run the risk of an explosion so BE CAREFUL!! the bottle goes rock hard when it’s done. put the bottle in the fridge for about 4 hours to stop the reaction, then very carefully release the pressure. sieve off the bits of ginger and drink. (it is alcoholic but only just, about 0.2 to 0.4%). mmmmm! nice!
