I'm all for simple when it comes to mixing up cocktails at home; this one certainly fits into that category. And it's delicious, too.
Everyone really liked them yesterday; I made them up just minutes before my guests arrived and kept them in the freezer until serving time so they were nice and cold.
If you are going to make them on the spot, it's a very nice touch to put your serving glasses into the freezer for a few hours beforehand.
One 12-ounce container of frozen Raspberry-Cranberry concentrate, or frozen Cranberry Cocktail concentrate
To mix: In a pitcher, mix the Raspberry-Cranberry concentrate with 1 1/2 to 2 containers of cold water (depending upon how fruity you want your drinks).
Pour a jigger or so of vodka into each glass and top with the diluted concentrate, stir.
If you prefer you can mix the drinks in a cocktail shaker.
