Beer

• 5 cups boiling water, cooled slightly
• 3/4 cup caster sugar
• 50ml fresh lemon juice
• 1 tbs ground ginger
• 1 tsp dried yeast
• 1 lemon, thinly sliced
• Fresh mint leaves, to serve

Combine the water, sugar, lemon juice, ginger and yeast in a large bowl. Cover loosely with plastic wrap and set aside at room temperature overnight to infuse. Skim off and discard the scum that has risen to the surface of the yeast mixture. Pour the mixture into a 8-cup capacity airtight plastic bottle but don't fill the bottle to the top. Place in the fridge to chill.
Divide the lemon slices and mint leaves among serving glasses, top with ginger beer and serve.
