750g frozen organic raspberries
85g fructose (available at supermarkets)
10 ml (2 tsp) vodka (optional)
Thaw the raspberries, then pur’e them in a blender.
Pass the pur’e through a coarse sieve to remove the seeds.
Weigh out 600g of the pur’e and add to a bowl containing the fructose and vodka if using.
Stir until the fructose has dissolved. At this point the sorbet base can be refrigerated until needed.
To prepare the frozen sorbet, pour the raspberry base into the bowl of a food mixer and, using the paddle attachment, begin mixing it at a slow speed. Crush the dry ice by wrapping in a tea towel and beating with a rolling pin.
Slowly add spoonfuls of crushed ice. Continue mixing and adding ice a little at a time until the sorbet has frozen. Serve immediately or place in the freezer.
