Just got back from Galiano Island doing some foraging for Pilgrimme restaurant, they made this fabulous salad of mizuni, wild mint, elderflower vinaigrette, and fir tips that myself and a few other people collected for the chef that day, best salad I’ve had all year. They also play a lot with seaweeds and I thought that you folk might be interested in learning a bit about how to harvest seaweed since we have so much of it on the Pacific coast and it’s so good for you.
How to harvest seaweed:
#1 First rule of forage club: Make sure the water quality is top notch, don’t harvest seaweed near cities or boats as they can dump their refuse right in the water. Go out to the Gulf Islands, the further away from humans the better.
#2 Generally, it’s best to harvest seaweed when the water is cold and clear, as the summer comes on the water gets murky and the flavour of the seaweed can suffer. It’s still okay to pick it in summer, but it tastes better in cold months.
#3 Harvest only from living plants that are still rooted to the sea floor, wait till low tide if you don’t have a boat so that you can hand harvest.
#4 Harvest only a small amount, seaweed is home to a lot of other creatures that rely on it for food or for breeding grounds, make sure you’re not taking more than your share. As with any food, consuming in small doses is best.
Types of seaweed that are good to harvest for beginners:
Sea lettuce – (Ulva lactuca) – bright green and grows in thin sheets in the inter-tidal zone so it’s easy to pick at low tide. A very clean tasting seaweed, not fishy, great in seaweed salad or add to ramen, congee or risotto for a colourful note of the sea.
Bull kelp – (Nereocystis luetkeana) – Very easy to identify but mostly you’d need a boat to harvest the live plant. Never pull the kelp out of the ground, just cut away what you’ll use so it can regrow. Great texture, try pickling it.
All of these seaweeds are so good for you, full of antioxidants, vitamins, minerals, fiber… a superfood punch that’s very plentiful and under utilized on our coasts.
An amazing app for our area is Seaweed Sorter that can help you ID seaweeds that are new to you.
