50g fresh bakers yeast
2 tsp ground ginger
2 tsp sugar
Start a Ginger Beer plant by placing 50g of fresh bakers yeast in a jar with about 300ml of water, 2 teaspoons of ground ginger and 2 teaspoons of sugar.
Feed the plant each day for the next 7 days by adding one teaspoon of sugar and one teaspoon of ground ginger.
Strain the mixture through fine muslin (keep the sediment) and reserve the liquid. Dissolve 450g of sugar in 600ml of boiling water. When cool, add the juice of two lemons and the reserved liquid and make up the volume to 4 1/2 litres.
Bottle, keep for one week, then, either drink quickly or keep refrigerated as it tends to become livelier with age.
Restart the plant by dividing the sediment into two parts and placing each half into a jar with 300ml of water. You now have two plants to feed as above. If one plant is enough, give one away
