Place watermelon in blender. Cover; blend until smooth. Pour puree into a pitcher and keep very cold, even a little frozen to make it icy.
For 2 martinis, add one cup of watermelon puree, 1/4 cup of lemon vodka, 2 tablespoons of lime juice, one tablespoon each of Cointreau and sugar to the blender with 3 to 6 ice cubes. Cover; blend until slushy.

While this classic warmer gets top billing around St. Patrick’s Day, it’s a welcome after-dinner treat on almost any occasion. Because the recipe is so elemental, it pays to use the best coffee and cream you can find—you will be able to taste the difference. Whip the cream softly so it sits in the glass in soft peaks. And as for that shot of whiskey? Any blended Irish whiskey—like Tullamore DEW, Redbreast, or the classic, Jameson—should do the trick nicely.
