Seaweed Tempura Crispy Nori (Printable Version)

Light tempura batter crisps seaweed sheets, paired with a savory dipping sauce, delivering an umami-packed snack.

# What You'll 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 chilled egg yolk

→ For Frying

08 - 2 cups neutral oil such as 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

# How to Make It:

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 desired. Set aside.
02 - Stack the nori sheets and cut each into quarters to create 32 pieces of uniform size.
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 ice-cold sparkling water. Pour this mixture into the flour blend and gently mix using 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, maintaining consistent temperature throughout frying.
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 nori pieces with a slotted spoon and drain on paper towels to remove excess oil.
08 - Arrange warm nori tempura on a serving plate and present with the prepared dipping sauce on the side.

# Expert Tips:

01 -
  • It takes fifteen minutes from prep to plate, which means you can impress people without spending your whole evening in the kitchen.
  • The dipping sauce hits that sweet-salty-tangy balance that makes you want to eat more than you planned to.
  • Once you nail the technique, it becomes your secret weapon for turning leftover nori into something restaurant-worthy.
02 -
  • The moment your batter gets warm or sits for more than two minutes, it loses its lightness and your nori comes out heavy instead of crispy, so work quickly and keep everything cold.
  • Don't overcrowd the pan when frying; three or four pieces at a time is the sweet spot, because crowding drops the oil temperature and you'll end up with greasy results instead of that shattered, golden exterior.
  • If your oil starts smoking or smelling burnt, take the pan off heat and let it cool slightly; burnt oil flavors everything negatively and there's no coming back from that.
03 -
  • Prep everything and have it ready before you turn on the stove, because tempura frying moves fast and you don't want to be chopping spring onion while your oil is at temperature.
  • If you end up with leftover batter, it doesn't keep well, so only make what you need; the lumpiness that makes great tempura is the same thing that causes the batter to break down if it sits.
  • Serve these within five minutes of frying for maximum crispiness, because even in a warm kitchen, the steam from cooling nori will soften the coating over time.
