Japanese Soy-Braised Hijiki Seaweed Pasta

Hijiki is a black sea vegetable with a distinct flavor, considered in Japan to be a source of health and longevity. Although its color might be intimidating at first, when combined with pasta and salty soy seasoning, you get a dish with deep, earthy umami flavor packed with minerals.

Instructions

1

Soak the hijiki seaweed in plenty of water for 15 minutes. You'll see it absorb water and expand.

Tip: Rehydrating dry seaweed is essential to get an edible, flexible texture.
2

Meanwhile, cook the pasta until 'al dente', then drain.

Tip: Don't overcook, as it will get more heat and sauce in the pan later.
3

Drain the expanded seaweed and rinse thoroughly under running water.

Tip: Rinsing washes away excess salt and sea-like aftertastes.
4

Heat oil in a skillet and sauté the crushed garlic for a few seconds.

Tip: Careful, garlic burns quickly; just release its aroma.
5

Toss in hijiki and edamame, drizzle with soy sauce, and sauté for 2-3 minutes.

Tip: Sautéing and caramelizing the soy sauce deepens flavors.
6

Fold in the cooked pasta and heat everything together so the noodles absorb the savory oil.

Tip: If it feels too dry, add a spoonful of pasta water (emulsification helps juiciness).
7

Serve sprinkled with toasted sesame seeds and fresh cilantro.

Tip: The crunch of sesame seeds contrasts excellently with the soft seaweed and pasta.
