Place the basil, chopped tarragon, tomato and horseradish in a fine strainer over a container. Place in refrigerator and allow to drip for 3 days. Discard contents of strainer. Add the vodka to the remaining liquid.
Blossom the gelatin sheets in cold water until soft. In a medium saucepan over medium heat, warm the herb-tomato liquid mixture to about 120 degrees fand dissolve the blossomed gelatin sheets in it. Using a small mellon-baller, cut the apple into small balls. Pour the gelatin-tomato liquid into 4 shallow 5 to 6-inch bowls. Garnish with cucumber, reserved tarragon leaves, and apples, dividing equally between bowls. Refrigerate for at least 1 hour.
In a small mixing bowl, place the stone crab knuckles, ver jus, creme fraiche, and powdered sugar. Mix lightly, trying not to break the crab too much. Lightly season with sea salt. Remove bowls from refrigerator; divide crab mixture evenly between the bowls. Top with micro greens that have been lightly seasoned extra-virgin olive oil and sea salt. Place crab on top and serve immediately.
