Raspberry Coolers
Coming soon to a market near you: sweet-tart raspberries. Use the fruit as the base for an aromatic syrup, and combine with seltzer for a refreshing sip. A few tablespoons of the mixture also enlivens white wine, vodka, and iced or hot tea. Make a double or triple batch to keep in the refrigerator. It will last for up to a week.
