I know it’s cold and the last thing you probably think about is to step out into the icy sea water and harvest some seaweed to cook over a campfire. But I tell you, it is a perfect time for it. Due to algae we usually say you should not harvest mussels in months that do not have an R in their names. I like to use that rule for everything else from the sea that you can get from the coast (aside from fish). In addition, I personally like to eat seaweed if it is taken from cold waters rather than on a hot summer day. It just seems more delicious in my opinion.
Seaweed is so extremely easy to prepare, and the good thing about it: in Denmark almost every seaweed is edible, although some taste better than other. Especially bladder wrack (Fucus vesiculosus) and toothed wrack (Fucus serratus). You can eat it raw, dry it over the fire or just put it in a pot and boil it for about a minute and eat as a side dish to some veggies or add them into the soup as well. You can also make tea from seaweed.
Of course, if you are allowed to light a fire on the beach, then it is easier to just cook it there. And if you cook fresh food over fire, it just adds more to the taste rather than if you wait till you get home. Although remember, if you plan to transport seaweed home, I advise you to keep it moist in seawater until you are home. Then it will not smell and get bad.
