Step 1Measure ice water into large mixing bowl. Sprinkle batter mix blended with baking powder over ice water. Stir just until ingredients are moistened; do not beat. Batter will be lumpy. If it seems too thick, add more water. Place bowl of batter into bowl of ice water to chill.
Step 2Heat oil in deep skillet to 375 degrees. Drizzle batter into pan, a portion at a time, so it just covers surface of oil and fries evenly. Fry until batter browns, turning to brown all sides, 3 to 4 minutes. Repeat, frying until all batter is used. Remove with slotted spoon to paper towels to drain. When fried batter cools, crumble into small pieces. Makes about 2 cups.
Step 1Combine soy sauce, lemon juice, rice vinegar, water, sugar, sesame oil and instant dashi. Cover and let stand until ready to serve salad.
Step 2For each salad, arrange 2 cups mixed greens on serving plate. Top with 1 cup cooked soba noodles, 1/4 cup bonito flakes, 2 tablespoons sliced green onion, 1 tablespoon prepared sesame seeds and seaweed and 1/4 cup crumbled tempura batter. Garnish with sprinkle of black sesame seeds.
