This is similar to my old Cranberry Vodka post from the archives. This is a nice light fruity vodka, then it is topped up with a sugar syrup.
Take about half a bottle of vodka and put raspberries in it - it's important they are torn or cut up - this releases the colour into the vodka. Then put a few pieces of lemon peel into the vodka as well. Shake a couple of times a day for two weeks. Keep in a cool place.
After a couple of weeks, sieve the vodka to remove all the raspberry and lemon bits, then make a sugar syrup, by heating up about 200g of sugar in 1 litre of water. Add this to your vodka and the bottle up in sterilised bottles.
