Build this cocktail in a half-gallon jar or a large pitcher. Combine:
¼ cup Blueberry Sage jam
1 large handful of shredded mint leaves
2 small limes, quartered and squeezed
2 cups white rum, or favorite flavored white rum
1 cup ice
Muddle jam, mint, limes and lime juice. Add ice and rum and shake ingredients together until the jam breaks down, the mint is fragrant, and the mix begins to froth-- about 45 seconds. Pour over crushed ice, adding club soda to dilute to desired strength.
