With or without the vodka, make this frosty cooler for a hot, summer brunch.
Place frozen cherry tomatoes, vodka, lime juice, horseradish, and hot sauce in the jar of a blender; season with salt and pepper. Puree until smooth but very thick. Divide among chilled glasses, and garnish with celery stalks and cherry tomatoes. Serve immediately.
For the best results, freeze the cherry tomatoes the night before you plan to make these frosty drinks.
