I have not found any ready-made raspberry vodka. The original Number 10 was made of pure spirit and Strands raspberry vodka essence. You can of course make it from fresh raspberries and vodka, but this can take some time. Fill the glass up to 1/3 with raspberry vodka. Scatter a few drops of Kahlúa into the raspberry vodka and mix it. Be careful, it's important not to get to much Kahlúa. Fill up the glass with Schweppes Russchian and the Number 10 is complete.
