Just for giggles I tried this recipe using my whitedog and fresh green limes.
It should work with any citrus.
Zest 4 or 5 medium sized green limes.
Add to a litre of 40% whitedog or vodka and leave for about two hours
Strain after the two hours and bottle
Add some sugar water to taste..... I used a teaspoon and a half per litre.
With the citrus oils in the skin it tastes fantastic and the colour is a bright green.
Drink with ice and water.
If too many limes are used the vodka will cloud when water is added.
