Crispy seaweed tempura snack (Printable)

Lightly battered fried nori pieces paired with a flavorful umami sauce.

# 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 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 - Combine soy sauce, mirin, rice vinegar, sugar, and sesame oil in a small bowl. Stir until sugar dissolves completely. Fold in sliced spring onion and sesame seeds if using. Reserve for service.
02 - Stack the nori sheets and cut each into quarters using a sharp knife or kitchen scissors, yielding 32 total pieces.
03 - Whisk together flour, cornstarch, baking powder, and salt in a mixing bowl until evenly combined.
04 - Lightly beat the chilled egg yolk in a separate bowl, then add the 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 neutral oil in a deep, heavy-bottomed pan to 350°F, monitoring temperature with a thermometer.
06 - Dip each nori piece briefly into the tempura batter, allowing excess to drip off, and immediately slide into the hot oil. Fry in batches to prevent crowding, approximately 30 to 45 seconds per piece until crisp and light golden brown.
07 - Remove the fried nori pieces with a slotted spoon and drain on paper towels to remove excess oil.
08 - Transfer the warm seaweed tempura to a serving platter and present alongside the prepared dipping sauce.

# Expert Suggestions:

01 -
  • Crispy seaweed transforms into something addictive that disappears faster than you expected, making this the kind of appetizer people actually remember.
  • Once you nail the technique, you'll find yourself making it for gatherings because it's vegetarian, impressively quick, and feels like you've been secretly taking cooking classes in Kyoto.
02 -
  • Don't prepare the batter more than five minutes ahead because it will get warm and lose that crucial lightness that makes tempura transcend ordinary fried food.
  • The moment you see the nori turn golden, pull it out immediately—that window between perfect and overdone is genuinely seconds, and waiting for color cues takes more experience than time.
03 -
  • Chill everything you can—egg yolk, sparkling water, even your mixing bowls—because the only thing standing between you and greasy tempura is keeping that batter as cold as possible until it enters hot oil.
  • Resist the urge to check on pieces too early or move them around in the oil, because that breaks the crust and lets oil leak in where it shouldn't be.
