I recently ordered ingredients from BC Kelp, a company in northern Canada that grows their own seaweed. A lot of the food I make these days has either nori, wakame, bull kelp or bladderwack whole tips in it.
I'd like to see more people cooking with sea vegetables. You can snack on dried seaweed, or add it to soups and salads. The powdered version I'm using in this recipe, adds a lot of umami and color to meals.
You can order your own bull kelp powder from the BC Kelp website, they have a wide range of quality seaweed to choose from.
