I'm not going to read the zillion pages, so please forgive me if I'm repeating a recipe. But for pure fun:
Make ahead frozen drinks.
1 12-oz can frozen fruit juice concentrate
12 oz distilled liquor
24 oz lemon lime soda pop (diet will work)
Mix, put in a plastic bowl in the freezer over night. It will freeze to the correct consistency if you stick to the proportions (if you skimp on the booze, it will freeze hard instead of slushy). I use the juice can as a measuring cup.
The origins of this recipe is limeade, rum, and 7up for a frozen dacquiri.
Most popular I've found is cranberry juice & vodka (lemon lime soda is the given for all the combinations) -- a frozen seabreeze
Grapefruit, vodka -- frozen greyhound
Grapefruit, gin -- frozen
OJ, Vodka -- frozen screwdriver
These are always popular, especiallly in hot weather, and leave your hands free to do other things.
