I use my fresh Cascades & Fuggles for what I call "Wet Hopping" while they're in season. I put them in my IPA or ESB kegs, but what I really like to do is put a fist full in a 2 liter soda bottle, fill it ~2/3 of the way with IPA or ESB, and put a Carbonator on it. I hit it with CO2 a couple times, and take it to picnics or similar outings. People really react to the floating cones and the intense aroma, it's great fun. Some people mention "grassy," but I don't get that much.
