I bought this for a bit of daft when family came for a visit, they are great fun. A tip for you though - use the powder jelly, if you use the block stuff make sure the total amount of liquid (jelly+water+booze) is not more than 200mls. The book also says to warm the molds to get the jelly out, DON'T DO IT !!! the jelly melts. Gently go arount the edge with a sharp knife. I could not find a cola jelly to add to the whiskey so I used gelatine and cola, it was ok but the cola tasted flat, you only need a double measure of alcohol so it's worth experimenting. Lemon and lime jelly and vodka - lovely !!!
