Wayne Collins prefers using premium, naturally sweetened tonic water (sometimes called Indian tonic water) in this punch. Q Tonic, made with agave nectar, and Fever-Tree, sweetened with cane sugar, are both excellent brands.
Bartender Phil Ward is obsessed with traditional recipes, which he learns by heart (he has a photographic memory), then tweaks. He cools his Kill Devil Punch with a block of raspberry ice that releases berries into the bowl as it melts.
According to mixologist Jeff Berry, this cooler is great for summer parties. Multiply each ingredient by the number of guests you're expecting, mix everything except the ginger beer and garnishes in a punch bowl and chill. Add a large block of ice (or ice cubes) and the ginger beer just before serving.
