Well that was quick and easy.
700ml of fermented liqour. (We need a name for this)
250ml barman's syrup (sugar dissolved in warm water)
1 bottle of coconut essence.
Mixed in the bottle.
Serve on the rocks.
The wife's words. "mmmmmm malibu"
Malibu costs $24 a bottle.
This stuff is legal to make and costs <$2 a bottle
If you forgo the carbon you can reduce the price by $10
