Editorial Guidelines Updated on January 17, 2019 Print Share Share Tweet Pin Email Servings: 3 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. Ingredients 2 pints raspberries 1 lemon, sliced ¼ inch thick (optional) 1 vanilla bean (split, seeds scraped, pod reserved) or ½ teaspoon pure vanilla extract ¼ cup sugar 3 cups seltzer Lemon wedges, for serving Directions Combine raspberries, sliced lemon (if using), vanilla bean, and sugar in a double boiler or heatproof bowl set over a pan of simmering water. Cook, stirring, until raspberries have released most of their juices, about 12 minutes. Strain through a fine sieve, pressing gently with the back of a spoon; discard solids. Let cool. Pour 1/4 cup syrup into each of 3 ice-filled glasses. Top each with 1 cup seltzer. Serve with lemon wedges. Print
