These Daikon Radish Boxes are topped with dollops of crab salad.
Cut the daikon radishes into 1 1/4-inch cubes (make sure the bottom is cut evenly so the cube will sit flat). Use a 1-inch melon baller to scoop out a bowl in the center of each cube.
Bring a pot of water to a boil, and blanch the daikon boxes for 3 minutes. Drain, and set aside.
Pick over the crabmeat, and discard any shells or cartilage. Place the crabmeat in a medium bowl, and add the diced cucumber, mayonnaise, lemon juice, mustard, salt, and 1 teaspoon chervil leaves. Stir the mixture until combined.
Place 1 heaping teaspoon crab salad into each daikon box, and garnish with remaining chervil leaves. Serve.
