The Cornish Seaweed Company

A small handful of photos, but they tell the story rather well.

A morning spent harvesting dulse and kelp from the Cornish coast. Clean waters and rocky coves. Buckets filled with deep red and golden fronds fresh from the sea.

Then, a little later, those same seaweeds finding their way into the kitchen in some form or another.

For many of our customers, dulse is where cooking with seaweed begins. It’s super easy to use, surprisingly versatile and brings a rich savoury depth to all sorts of dishes.

Our cookbook was created to make that first step feel a little easier, sharing simple recipes alongside the stories, places and people behind the harvest.

This butterbean stew is one of our favourites (although not from our cookbook, but we thought we’d give it a shoutout, as beans seem to be very in vogue right now!)

Simple ingredients, cooked slowly, with a little dulse (whole or flaked) stirred through, or popped on top.

Some seaweedy bowl inspiration 💡.

For us, using seaweed on pretty much a daily basis is a no-brainier.

When we’re not using it as the main event on the plate, it’s so simple as a sprinkle to add umami to the plate - just as you would add your salt and pepper as seasoning.

We’ve started publishing new recipe content to our website lately (this is content that is seperate from our cookbook “The Seaweed Cookbook”) so if you’re looking for new weekly recipes, head over there 👉.

We also recommend “The Seaweed Cookbook” if you’re new to seaweed, as it includes guides and properties of edible seaweeds, and cooking tips as well and recipes.

It’s Earth Day, and it feels like a day to be positive about our marine ecosystems, but to acknowledge that’s progress is mercurial - there’s always going to be more to get done if we want our waters to be a hapoy and healthy home for its living tennats.

We’ve backdropped some marine wins and stats against these absolutely exceptional photos of our harvesting process by the superbly talented .camera. Do check out his work.

Toast is a vessel for pretty much anything (even seaweed!)

Here we have some seaweed toast inspiration for you, all delicious and all benefitting from extra nutrients thanks to the presence of seaweed.

- Mushroom, three cornered leek, dulse flakes sautéed in butter.
- ⁠Sea Spaghetti, beef tomatoes (from Mr Ragamuffins) spring onion, rubbed garlic on the toast.
- ⁠Ocean Greens sautéed in butter and chili flakes, goats cheese, capers, Cornish Seaweed Pepper.

The Ocean Greens fried in butter are so tasty on their own! We’ve also included a little clip of the sea spaghetti in the pan - it goes from black (in its dried packaged state) to bright green when cooked) which is quite cool!

With turbulent weather comes a block on using the boat to access our harvesting sites, so it’s been a lot of carrying buckets of seaweed on our backs up the cliff instead! A good winter workout 💪

It’s been the season of Irish moss (also known as sea moss), which we take back to the processing site to be washed and dried by sunlight (which we could do with right about now!) 🌞

Sun-bleaching Irish moss removes the flavour of seaweed, allowing it to be used as a flavourless natural gelatin for recipes like panna cotta, and to thicken soups and stews.

Learn more about how to use Irish moss with the link in the comments 👇.

Did anyone else get a glimmer of hope that outdoor cooking might be back on the menu soon… 🌞?!

We were reminiscing back to the Cornish autumn of last year, when we were very fortunate to get out and cook outside with some amazing organic Cornish produce, including our seaweed.

You may have seen the Dulse and Sweetcorn Burgers (photo number 2) in our cookbook (a really fun one to try with the kids as it’s super tactile and if you’re outdoors, the mess and post-burger clean up isn’t so daunting 😅)

We've also got Dulse Butterbean Stew here, topped with whole Dulse (you can also use whole kelp, or flaked seaweeds sprinkled on top). The velvety, creamy texture of the beans really brings our the umami of the dulse in droves.

A staple is Sea Spaghetti, which we’ve mixed here with tagliatelle. It adds extra depth of texture and flavour, and of course, more vitamins and minerals. We’ve just added some raw garlic, tomato, lemon and spinach rather than making a sauce, making it a bit easier to do as a 1-pot.

The last photo may look like an outlier, but we use Seaweed Thins (or biscuits) for picnics all the time! The seaweed is very subtle in these, but it adds an extra salty twang when topped with your favourite cheese 😊.
