the sw website suggests hartleys jelly, then add the jelly snakes from a sweet shop and let it set!.. i always do 1/2 pint boiling water then top to 1pt with diet lemonade instead of water, cos it tastes better! the snakes are 1/2 each, but it'd look fab and after splitting it up at taster eve you wouldnt eat a whole snake to yourself anyways!
