Seaweed is …


Iodine is the most notable mineral found in seaweed. It is an essential nutrient that helps maintain thyroid health.


It grows fast. It doesn’t need soil to grow. Seaweed absorbs carbon dioxide and produces more than half the oxygen we breathe.


Seaweed has a depth of umami that makes any meal flavour-full. Umami is the fifth taste that makes you want to smack your lips. It’s the deliciousness in your food.

Seaweed, Miso & Sesame Furikaké

Like salt and pepper in the western diet, this is a versatile do-it-all seasoning that everyone loves.

Slightly sweet and crunchy with subtle umami. The heroes of this seasoning are the organic Tasmanian-produced chickpea miso, toasted sesame, sea salt and a tiny pinch of brown sugar to balance the saltiness.

Also available in bulk packaging.


Rainbow Seaweed Chilli Seasoning

Rainbow Seaweed™ Chilli Seasoning

A versatile seasoning for everyday meals. With a touch of sumac and cracked pepper, this medium heat seasoning makes things exciting without tears.

Perfect for those who like a little spice but aren’t competing in a hot-wings eating competition.

Add it to pasta, mac ‘n cheese, soups or even BBQ rub. Our seaweed blend adds a touch of umami without the strong fishy taste.

Also available in bulk packaging.

Australian Wakame

Tasmanian Wakame is an excellent source of iodine and a great salt substitute.

Our Wakame is harvested from the cleanest waters in the Southern part of Tasmania. It’s sustainably hand-harvested only six weeks a year. That too during winter.

Wakame flakes can ve added directly as a sprinkle or rehydrated before use. It’s crunchy when dry but has a chewy texture as it absorbs moisture.
