“I’m often asked what my obsession with seaweed is. I tell them how generations of women in my family swore by it to cure every ailment going." 

Founder of WASI Irish Seaweed Pesto, Claire O'Sullivan's great grandmother lived to 103 and her grandmother to 100, attributing their longevity to the healing power of seaweed.

"Seaweed is far more nutrient dense than any land vegetable and is an excellent source of micronutrients including folate, calcium, magnesium, zinc, iron, and selenium. More importantly, it's a great source of iodine." 


Claire and her partner Eli have developed several flavours of delicious WASI Irish pestos from the sea vegetables that grow in abundance around their home in West Cork. Their Wild Irish Seaweed Pesto flavours include garlic and lemon, chilli and lemongrass and ginger and sesame. Their pestos are delicious on a slice of toast or added to any sauce for a wonderful umani flavour. 


WASI's hard-harvested seaweed pesto is made from the freshest seaweed straight from the Atlantic. They mix age-old tradition with 21st-century techniques to bring you a delicious pesto from tide to table. 

"Collecting seaweed is our favourite stage in the creation of our pestos...Once back home the real work begins, washing, blending, sterilising and jarring. 


We make small batches each week with fresh, locally sourced ingredients...there's a certain pride to be felt knowing we're bringing to life the foods our ancestors valued so highly in our little glass jars."

WASI pesto is delicious with baked fish, crackers and cheese or mixed through pasta. How will you eat yours?
