I’ve been accenting the sweetness of summer watermelons with the bitter bite of Campari for years…which means I should have thought of this Watermelon Negroni cocktail sooner.Note about Watermelon Campari Ice Cubes: Although you can simply blend and strain watermelon chunks for juice, I cut a hole in one end of a watermelon, insert a stick blender and pull the trigger. It takes a couple of minutes and a bit of butter-churning up and down action, but you can basically liquefy the entire thing and with no mess. Then simply pour straight out into a strainer to remove the seeds and pulp.This recipe first appeared on altonbrown.com.
