Fizzy Ginger Cocktail With Pickled Watermelon Rind Recipe

Using a vegetable peeler, remove outer green layer of skin from watermelon (if you have a smaller watermelon, cut the bottom and top ends off so you can stand your watermelon up to peel. If it's larger, cut in half to stand up). Discard skin. Cut rind into 1-inch cubes and reserve pink flesh for another use.
Combine apple cider vinegar, sugar, water, salt, cinnamon sticks, peppercorns, bay leaf, chili pepper flakes, cloves, and coriander seeds in a medium saucepan and bring to a boil. Add watermelon rind, return to a boil and boil for 10 minutes, stirring occasionally. Remove from heat and carefully place a heatproof plate on top of the rind to keep it submerged as the mixture comes to room temperature.
Once cool, transfer entire mixture to an airtight container and let stand in refrigerator for at least 2 days and up to 2 weeks.
Combine vodka and ginger in an airtight container. Let stand in a cool, dark place for 5 days or to your desired spiciness, up to 14 days total. Strain into an airtight container and store at room temperature for up to 6 months.
Combine Ginger Infused Vodka and vermouth in a mixing glass and fill two-thirds full with ice. Stir until well chilled, about 20 seconds. Strain into a small wine glass or coupe. Top with Prosecco and garnish with the pickled watermelon rind.
