Recipe Notes

Dave Arnold recommends adding sugar to your alcohol beforehand. You can add 159 grams of sugar to a 750 ml bottle of alcohol at 40-50% ABV if you want to have a bottle dedicated to making frozen drinks. That's not such a bad thing.

Superfine sugar is best because it dissolves quickly. You can use granulated sugar, but it will take longer to dissolve.
