Having no idea what the recipe would be to make Jasmine vodka, we followed ginfool's recipe for Elder Flower infusions. "Elderflower 1/3cup :1cup 28 hours. New Amsterdam much more successful than Tanqueray. Lighter and more floral result. Try it with ginger and simple syrup and/or ginger ale."
375 ml Fris. That translates to ~1/2 cup of Jasmine flowers for 375ml of vodka. We used the kitchen scale to measure that 1/2c jasmine flowers weighs 3/8 oz. Infusion started 10.31.11 at 10:30pm. E thinks we need to be careful because this one could turn bitter quickly.
