When you think of seaweed, what first comes to mind? Is it the slimy stuff you see on the beach? Or are you like me and see a super-nutritious ingredient full of awesome health benefits that deserves to be included more regularly in your diet?

As a surfer, I’m a bit of sucker for any flavour or texture that comes from the ocean. Add to that the fact that seaweed is one of nature’s most nutritious (and oldest) plants and imparts a delicious salty, umami flavour to everything it touches and I’m sold on the slimy stuff.

Nutritious & sustainable

One of the world’s most sustainable food sources, seaweed represents up to 15 per cent of the average diet in Asian countries such as Japan. Yet in Western societies, such as Australia and the US, we’re really only just catching the current on the true health benefits of seaweed.

Seaweed requires no fresh water, no land and no fertiliser, so this vitamin-dense ingredient that can feed many is very easy to produce in a sustainable way.

Rich in iodine, potassium, magnesium, calcium and iron — as well as vitamins, antioxidants, phytonutrients, amino acids, omega-3 fats and fibre — just one serving of seaweed can provide your body with many key nutrients our modern-day diets lack. It can also be used as an alternative to salt because it provides a salty flavour with more nutrients and a smaller percentage of sodium.

While there’s no denying it packs a punch in flavour and nutrients, the other really cool thing about seaweed is it’s a future food — one that’s available in the wild all year round, naturally regenerating and able to be cultivated sustainably. Seaweed requires no fresh water, no land and no fertiliser, so this vitamin-dense ingredient that can feed many is very easy to produce in a sustainable way.

Delicious umami

I also love that seaweed is one of the oldest (and first) plants to ever grow on Earth: seaweed is said to have been in existence for 3.5 billion years. It was used in cooking 3000 years ago and was a staple in every ancient culture on every continent, from Scandinavia to the Americas to the Pacific Islands. Plus, given that different seaweeds grow in different oceans, its uses and traditions varied with available species and climate.

For example, Japan has a tradition of eating kombu that goes back several centuries. Traditional Okinawan cuisine relies heavily on kombu with Okinawa using more kombu per household than any other region of Japan.

Whenever you add an umami-rich food such as seaweed into a broth, it gives it a heartier, fuller flavour.

The reason kombu (better known as kelp in Australia and NZ) is used so much in cooking in Japan is because of the strong flavour the seaweed imparts to any dish. Umami (as this flavour is known) is the cornerstone of dashi, a delicious, classic Japanese seaweed soup used in everything from miso soup to salad dressings.

Interestingly, umami was named by Kikunae Ikeda, a chemist who discovered in 1908 that it was the glutamates in the seaweed soup that made it taste so good. Glutamine is one of the 20 amino acids encoded by the standard genetic code and is known to be superb brain food. However, it would take scientists until 2002 to actually identify umami as a fifth taste, along with sweet, sour, bitter and salty.

Whatever its history, as a chef I know that whenever you add an umami-rich food such as seaweed into a broth it gives it a heartier, fuller flavour. Dashi is made from kombu, a brown seaweed. I love infusing kombu for a stock. You simply place all ingredients except the kombu into a pot and simmer slowly. Once it has simmered for 15 minutes, you can add in the kombu strip and steep for at least 10 minutes.

Like all good broths, this flavourful, nutritious stock can be used as a base for soups, stews and gravies. It’s also used throughout Asian cultures as a daily drink to help strengthen the body.

Health benefits

The other reason I reckon these sea vegetables are seriously cool is that seaweed has so many health benefits.

In broad terms, there are three types of seaweed — the aforementioned brown (kombu/kelp), red (dulse, agar and karengo) and green (sea lettuce) — and each one as a bucketload of different nutritional benefits.

Brown seaweeds, for example, are typically rich in iodine and can be used to help nourish the thyroid gland and brain. However, if you do have thyroid issues, you may wish to consult your healthcare practitioner as to what’s best for you. This type of seaweed is also an awesome way to help detoxify the body from heavy metals and environmental toxins.

Along with kombu/kelp, other popular brown seaweeds you can buy from your local Asian supermarket include wakame and sea spaghetti.

Red seaweeds, meanwhile, are the oldest and largest group of algae with over 6000 species worldwide. Their distinctive pigments allow them to survive at great depths and the most popular red species include karengo (aka nori or laver), dulse, agar and sea chicory.

 Using seaweed

I really love to include karengo in my diet as much as possible. Karengo is a nutritious species of nori found in New Zealand and, from a culinary perspective, I reckon it’s one of the most delicious. The key to serving karengo well is to take care with how you prepare it, as it’s delicate and will burn under intense heat. I love to serve it straight from the packet on top of eggs or we use it dried in one of Nic’s salads because it packs a nutritious punch while providing a really good nutty flavour. When karengo is wet, it works well in Mediterranean dishes or in soups because it has a mild anchovy flavour.

Red seaweeds are an excellent source of minerals, carbohydrates, antioxidants and enzymes, and are generally very high in dietary fibre. They are also rich in agar and carrageenan and have a positive potassium/sodium balance. These varieties of seaweed have excellent anti-viral and anti-bacterial properties and are a good way to improve the body’s resistance to stress.

Unlike red seaweeds, which occupy the deep, green seaweeds grow closest to the shore and are related to land plants. Known as “emeralds of the sea”, green seaweeds have more minerals than many land-grown vegetables and include a large amount of digestible vegetable protein. They are also an excellent source of chlorophyll.

I like green seaweeds because they are a good way to improve digestion and reduce sugar absorption. They are also known as a natural remedy for gout.

While there are many different species of seaweed and many diverse ways you can use them in the kitchen, the one thing I must flag is — as with any ingredient you use — you should know your source.

It’s something that’s particularly important when it comes to selecting the type of seaweed to cook with because you want to choose seaweed that comes from clean oceans. My suggestion is to source local, wild or sustainably farmed seaweed from the South Pacific Ocean.

Next time you head to the beach, think again when you climb around the rocks and over all that “slimy stuff” just what amazing things it can do for the health of you and your family. And the next time you cook in the kitchen, think about including seaweed somehow because it truly is one of the most nutritious ingredients available in King Neptune’s bounty.

Nori Chips With Sesame

Serves: 2–4

Ingredients

Method

  • 1 tbsp sesame seeds
  • ½ tsp Himalayan salt
  • 1 tbsp sesame oil
  • 8 sheets nori
  1. Preheat the oven to 180°C.
  2. Using a mortar and pestle, grind the sesame seeds and sea salt to a coarse powder. Dip a pastry brush in the sesame oil and brush the nori sheets with it, covering each whole sheet with a light coating. Place the oiled sheets on baking trays, without overlapping. Place in the oven to toast for 4–5 mins.
  3. Remove from the oven and sprinkle with the sesame salt while hot. Cut into snack-sized squares and store in an airtight container.

Japanese Pork Ramen Soup

Serves: 4

Ingredients

Method

  • 1.6L chicken bone broth
  • 1 piece dried kombu, rinsed
  • 3 tbsp bonito flakes
  • 3 tbsp tamari
  • ½ tsp Chinese five spice
  • 1 tsp coconut sugar
  • 600g boneless pork shoulder or pork belly, skin removed & cut in half
  • 10 fresh shiitake mushrooms
  • 4cm piece ginger, julienned
  • 100g enoki mushrooms, trimmed
  • ½ daikon, spiralised into thick noodles

Reduce the heat to low, add the kombu, bonito flakes, tamari, Chinese five spice, coconut sugar and pork, cover and simmer for 2½–3½ hours until the pork is tender. Remove the pork from the liquid, discard all the fat and shred the meat. Cover with foil and set aside in a warm spot.
  2. Strain the broth into another large saucepan and discard the bonito and kombu. If the flavour of the stock is too intense, simply add a little water. Place the pan over medium heat and bring to a simmer. Add the shiitake mushrooms and ginger and simmer for 10 mins, then add the enoki mushrooms and daikon noodles and cook for 2 mins until the vegetables are cooked through. Season with salt.
  3. Meanwhile, place the wakame in 500mL of cold water and soak for 10 mins. Drain and set aside until needed.
  4. Divide the mushrooms, daikon and ginger between serving bowls. Arrange the shredded pork, wakame and egg on top, then ladle on the broth over and serve with the spring onion, shiso leaves and a few pinches of shichimi togarashi.

Steamed Salmon With Nori & Asian Greens

Serves: 4

Ingredients

Method

  • 20g (about 1 cup) bonito flakes, plus extra to serve
  • 1 dried kombu sheet, rinsed
  • 3 tbsp tamari
  • 1¼ nori sheets
  • 4 × 150g salmon fillets, skin removed & pin-boned

  1. Combine the bonito flakes, kombu and 1.25 litres of water in a large saucepan over medium–high heat, bring to the boil, take off the heat, then add the tamari and set aside to infuse for 10 mins. Strain the broth into a clean saucepan.
  2. Cut the nori into four 7cm×20cm strips. Wrap a nori strip around each salmon fillet. Set aside.
  3. Fill a saucepan with 1.5 litres of water and add the ginger. Place a bamboo steamer over the pan and bring to the boil. Place the salmon in the steamer, cover and cook for 4–5 mins until the fish is slightly pink in the centre.
  4. Bring the broth back to the boil over medium heat, stir in the miso, then add the choy sum and shiitake mushrooms and simmer for 5 mins, or until the vegetables are tender.
  5. Divide the vegetables among four serving bowls, pour over the broth, top with a piece of salmon, then scatter on the shiso and extra bonito flakes and serve.

Chicken & Egg Sushi Roll

Serves: 4–6

Ingredients

Method

  • 6 free-range organic eggs
  • 1 tbsp coriander, chopped
  • Pinch sea salt
  • 2 tbsp coconut oil

  • 4 toasted nori sheets
  • 2 cooked chicken thighs, shredded
  • 2 tbsp homemade mayonnaise
  • 1 avocado, sliced into strips
  • 1 small carrot, sliced into thin batons
  • Toasted white & black sesame seeds, to serve
  • Tamari, to serve
  • Wasabi, to serve
  1. Mix together the eggs, coriander and a pinch of salt in a bowl and set aside.
  2. To make the omelette, heat an 8-inch non-stick pan over medium heat and add 1 teaspoon of coconut oil. Once the coconut oil is hot, add 5 tablespoons of egg mixture to the pan and swirl the pan to coat the base with the eggs. Cook until the egg mixture is lightly golden underneath and moist on the top (40–60 seconds). Slide the omelette out of the pan and onto a cutting board. Repeat with the remaining egg mixture to form four omelettes. Set aside to cool.
  3. Place a nori sheet on the workbench or bamboo sushi mat. Lay a piece of omelette on top and trim the top and bottom edges of the omelette so it’s even with the nori sheet and the omelette is not overhanging.
  4. Spread on one teaspoon of mayonnaise, then layer the chicken, avocado and carrot across the edge closet to you. Begin to tightly wrap the roll all the way to the end. Trim the ends with a sharp knife, then cut into 2cm round pieces. Repeat with the remaining nori, omelette and fillings.
  5. Place the sushi pieces on a platter and sprinkle with sesame seeds, tamari and wasabi.
  6. Variation: Swap the carrot for 4 tablespoons of fermented kimchi.

Tuna Tartare On Nori Crisps

Serves: 6

Ingredients

Method

  • Nori Crisps
  • 150g (1½ cups) tapioca flour
  • 150mL (⅔ cup) ice-cold sparkling mineral water
  • Melted coconut oil, for frying
  • 3 nori sheets, each cut into 6 even squares
  • 3 nori sheets, each cut into 6 even squares

  • Tuna Tartare
  • 250g best-quality sashimi-grade tuna
  • ½ avocado, peeled & pitted
  • 1 tbsp sesame oil
  • 1 tbsp peeled and grated fresh ginger
  • 2 tbsp yuzu juice
  • 2 tbsp wheat-free tamari or coconut aminos
  • ½ tsp chilli oil (optional)
  • 2 tbsp lemon-infused olive oil
  • 1 tsp toasted white sesame seeds
  • Fresh baby coriander leaves, to garnish
  1. To make the nori crisps, put the tapioca flour in a mixing bowl and slowly pour in the mineral water while you whisk. Continue whisking until the batter has the consistency of pouring cream.
  2. Add oil to a depth of 10cm to a wok or deep saucepan. Heat the oil to 160°C. Dip each nori sheet, one at a time, into the batter to coat completely, then slide it straight into the hot oil. (The nori sheet will become very soft very quickly once it is covered in the batter, so it’s best
to put it straight into the frying oil after coating. Do this in batches.)
  3. Fry the nori on both sides until light and golden, about 30 seconds. Drain on paper towels and sprinkle with sea salt.
  4. To make the tartare, dice the tuna into small pieces and place in a chilled bowl. Dice the avocado the same size as the tuna and add to the tuna with sesame oil, ginger, yuzu juice, tamari, chilli oil, if using, and lemon oil. Mix until combined and season with salt and freshly cracked black pepper.
  5. Spoon a teaspoon of the tuna mix on a nori crisp, and sprinkle with some toasted sesame seeds and coriander. Repeat until all the crisps and tartare are used.
