Place the tomatoes, mint, garlic, lemongrass, chopped scallion and
jalapeno in a
blender and
pulse until still chunky but releasing liquid.
Line a fine sieve with a double layer of
cheesecloth over a large container. Pour the tomato mixture into the
sieve and let
drain for 2 to 3 hours, or refrigerate overnight.
Season the strained liquid with salt and pepper. Pour into shooter glasses,
garnish with the grape tomatoes and sliced scallions.
