PORTO COOLER

While coolers are often stretched with something sparkling, this rosehued drink swaps in a pour of fresh watermelon juice. DAVID MALOSH/ THE NEW YORK TIMES PHOTOS

Makes: 1 cocktail

6 to 8 very thinly sliced citrus wheels, such as lime, lemon and orange, preferably using citrus with thin piths

Ice

2 ounces white port

1 ounce blanc vermouth 4 dashes orange bitters, or use Angostura

3 to 4 ounces dry tonic

In a wider-mouthed highball glass, tuck the citrus wheels around the sides of the glass, adding ice as you move up the glass. (The ice will help keep them in place.) Add the port, vermouth and bitters. Tuck a straw into the glass and top with tonic.
