Boxed sea urchins, foods from both land and sea, and tempura to start. The tempura, fried in blended oil, is light and airy. The secret is in the batter: to reduce gluten, wheat flour is chilled to below freezing before frying. One inventive dish is tempura of sea urchin and nori seaweed. Combinations are delightful, including eel grilled without seasoning then brushed with wasabi, and Orient clams dressed with pepper flowers.
