This is a winter twist on a classic summer cocktail! I love kumquats because they are tangy with a hint of sweetness. When in peak season, they're so juicy they explode with freshness to wake you up from the winter blues.
Add the whole kumquats, mint and sugar to a small pitcher. Muddle until the mint leaves are broken down, the sugar is dissolved, and the kumquats are softened.2.
Add the lime juice and seltzer and stir to combine. Strain into 2 tall glasses filled with ice.3.
Garnish with mint sprigs and the kumquat slices.
