Liz originally found a similar recipe in Gourmet while lying on the beach on Long Beach Island. Greg immediately rose from his chair on the sand and proceeded to buy a melon, slice it up and throw it in the freezer to be ready by 5 p.m.
The secret of this drink is that it has no ice, which weakens flavors and makes a standard frozen margarita undrinkable. Here, the frozen melon provides the chills and makes for a concentrated melon flavor. Seeds may be left in the melon because they will be pulverized by the blender blades and leave behind a lovely speckling throughout the drink. Sissies may wish to buy seedless melons.
Recipe, which has changed quite a bit from the original Gourmet inspiration, after the jump.
Combine all ingredients in a blender and crush the watermelon as if it were ice. You want a slushy texture; not a true puree. Salt the rim of glasses, if desired, and pour the frozen margies into the glasses. Garnish with a lime.
Makes about 10 drinks.
