3/8 cup (3 ounces) whole milk
About 3/4 cup (6 ounces) very cold seltzer
3 tablespoons (1 1/2 ounces) chocolate syrup
Straight pretzel rod, for garnish
Pour the milk into a 12-ounce glass and add the seltzer. Using a long spoon, stir vigorously for a few seconds. Gently pour the chocolate syrup into glass, then stir again, taking care to stir mostly at bottom of glass to incorporate. Garnish with the straight pretzel rod.
Makes 1 serving.
