Gently warm (microwave) a fat teaspoon of wild elderberry jelly with a teaspoon of water, to make a smooth syrup. Add to other ingredients and stir. Fine strain into a rocks glass over ice.
A little clumping of the jelly is normal, but fine straining removes that. Have also made this drink straight up, either shaking with ice, or stirring and fine straining into a well-chilled Irish coffee glass. Either Pierre Ferrand Ambre or 1840 works well. The elderberry jelly is available from American Spoon.
