Let's dive into the simple steps to create this Japanese classic.

  • Seaweed: 8 large nori sheets
  • Tempura Batter: 100 g (3/4 cup) all-purpose flour, 30 g (1/4 cup) cornstarch, 1/2 tsp baking powder, 1/2 tsp fine sea salt, 200 ml (3/4 cup + 1 tbsp) ice-cold sparkling water, 1 large egg yolk, chilled
  • For Frying: 500 ml (2 cups) neutral oil (canola or sunflower)

Instructions

1. Prepare the dipping sauce
In a small bowl, combine soy sauce, mirin, rice vinegar, sugar, and sesame oil. Stir until sugar dissolves. Add sliced spring onion and sesame seeds. Set aside.
2. Cut the nori
Stack the nori sheets and cut each into quarters to make 32 pieces.
3. Mix dry ingredients
In a mixing bowl, whisk together flour, cornstarch, baking powder, and salt.
4. Prepare the batter
In a separate bowl, lightly beat the chilled egg yolk, then add the ice-cold sparkling water. Pour this mixture into the flour blend and gently mix with chopsticks or a fork. Do not overmix; the batter should remain slightly lumpy and cold.
5. Heat the oil
Heat the oil in a deep, heavy-bottomed pan to 180°C (350°F).
6. Fry the nori
Dip each nori piece quickly into the tempura batter, allowing excess to drip off, and immediately slide it into the hot oil. Fry in batches to avoid crowding, about 30–45 seconds per piece, until crisp and lightly golden.
7. Drain
Remove with a slotted spoon and drain on paper towels.
8. Finish and serve
Serve warm with the dipping sauce.

Zusatztipps für die Zubereitung

For the best results, ensure the sparkling water is ice-cold. This creates a temperature shock when the batter hits the hot oil, leading to a lighter, more delicate crust. Using chopsticks to mix the batter prevents overworking the gluten, which keeps the tempura from becoming bread-like.

Varianten und Anpassungen

If you prefer a spicier profile, add a pinch of chili flakes directly into the batter. For those who want maximum crunch, you can double-coat the nori sheets. You can also experiment by swapping standard nori for other types of edible seaweeds or adding a touch of aonori (dried seaweed powder) to the flour for extra color.

Serviervorschläge

These crispy seaweed pieces are best enjoyed immediately while still warm. Serve them as a finger food alongside a cold Japanese beer or a cup of hot green tea. They also make a fantastic topping for rice bowls or a side for a bowl of udon noodles.
