Scumelicous Ginger Beer

I'm spending the weekend developing new 'ginger' products, I want to extend the range of scrummys! So I've found a recipe for old fashioned ginger beer-lashings of it! And it's so easy to make, with 5 simple ingredients - water, sugar, yeast, lemon juice and grated ginger. It all goes in a pop bottle and is left to rest overnight in a warm place, next morning you can taste it, the mixture positively fizzes as you loosen the bottle top, and the pale golden  contents gently sparkle in the glass.  Verdict - it's refreshing and an absolutely scrumelicous delight!
