I am a huuuge fan of gin, and my favorite way to partake of it is the gimlet, which is simply gin and lime juice. I've been itching to try a recipe from July's issue of Bon Apetit for a cucumber gimlet, and I think that tomorrow's picnic will be the perfect occasion. I'll report back with my impression, but here's the recipe.
2 large cucumbers
1/2 cup gin
4 teaspoons fresh lime juice
1 tablespoon sugar
1 cup ice cubes
4 lime slices
Slice four 1/4-inch-thick slices from 1 cucumber. Peel and coarsely chop remaining cucumbers; transfer to processor and puree until smooth. Pour through fine strainer set over large bowl, pressing on solids in strainer. Discard solids in strainer.
Mix 1 cup cucumber juice, gin lime juice and sugar in pitcher; stir until sugar dissolves. Add ice; mix well. Immediately strain mixture into 4 small martini glasses. Garnish with lime and cucumber slices and serve.
