Planning a New Year's Eve party? There's a lot you'll need to buy. A bottle of wine holds four to six glasses. Champagne, while the same in size, goes a bit farther. "Fifths" (4/5th- quart bottles) make from 10 to 16 cocktails. For mixes, get club soda, tonic and ginger ale, and have plenty of soda and soft drinks on hand, too. You'll need 1 pound of ice per person. Sixteen people means 16 pounds of ice (you'll want even more if you're chilling bottles or cans). And, don't forget juices like tomato, orange, apple and cranberry. Today many prefer juice and soda or sparkling mineral water to a cocktail. Don't forget garnishes like lemon and lime, olives and bitters. To make 25 cups of coffee, you'll need a half-pound and almost a gallon of water. And that's the On The House tip for today.
