That passion fruit juice and vodka is dead simple. A few ounces of good vodka and the rest chilled passion fruit juice to make a 10 ounce drink. No ice. It just waters things down if it's given a chance to melt. The key is to drink it fast enough so that it doesn't warm up. :-) BTW, I use Grace brand because that's what I can find, and I can't find it all the time. When I do find it I buy all of it.
