Seaweed Tempura Snack (Printable)

Enjoy crispy fried nori coated in a light batter, served with a savory umami dipping sauce for a flavorful snack.

# What You Need:

→ Seaweed

01 - 8 large nori sheets

→ Tempura Batter

02 - 3/4 cup all-purpose flour
03 - 1/4 cup cornstarch
04 - 1/2 teaspoon baking powder
05 - 1/2 teaspoon fine sea salt
06 - 3/4 cup plus 1 tablespoon ice-cold sparkling water
07 - 1 large egg yolk, chilled

→ For Frying

08 - 2 cups neutral oil (canola or sunflower)

→ Dipping Sauce

09 - 3 tablespoons soy sauce
10 - 2 tablespoons mirin
11 - 1 tablespoon rice vinegar
12 - 1 teaspoon sugar
13 - 1/2 teaspoon toasted sesame oil
14 - 1 spring onion, finely sliced
15 - 1/2 teaspoon sesame seeds, optional

# Directions:

01 - In a small bowl, combine soy sauce, mirin, rice vinegar, sugar, and sesame oil. Stir until sugar dissolves completely. Add sliced spring onion and sesame seeds if using. Set aside.
02 - Stack the nori sheets and cut each into quarters to yield 32 pieces.
03 - In a mixing bowl, whisk together flour, cornstarch, baking powder, and salt until evenly combined.
04 - 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.
05 - Heat the oil in a deep, heavy-bottomed pan to 350°F.
06 - 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, approximately 30 to 45 seconds per piece, until crisp and lightly golden.
07 - Remove with a slotted spoon and drain on paper towels.
08 - Serve warm with the prepared dipping sauce.

# Expert Tips:

01 -
  • They're ready in 25 minutes flat, which means you can impress people without spending your whole afternoon in the kitchen.
  • The contrast between the shattering crispy exterior and delicate seaweed feels like a tiny celebration in your mouth every single time.
  • Once you nail the technique, you'll find yourself frying these for every gathering because they disappear faster than you can make them.
02 -
  • Overmixing the batter is the biggest mistake—lumps are not a sign of failure but proof that your tempura will be crispy and delicate instead of dense and heavy, so resist the urge to make it perfectly smooth.
  • The temperature of your ingredients matters more than you'd think; everything should be chilled because warm batter won't create that ethereal texture, and warm oil below 350°F will absorb grease instead of sealing the coating instantly.
03 -
  • Keep everything cold—your ingredients, your batter bowl, even briefly chill your nori sheets—because cold batter against hot oil is what creates that shattering contrast that makes people come back for more.
  • Fry in small batches and never crowd the pan because each piece needs space to bubble and crisp without steam from its neighbors making it soggy; patience with batching is the difference between restaurant-quality tempura and soggy disappointment.
