Seaweed has become the superhero of Irish foods. Broccoli would genuflect in its presence.

This recipe has been passed through neighbours, family and friends for 20 odd years. It’s swinging with crucial trace minerals and seems to be anti-viral plus anti-bacterial. (Then again, the placebo effect can still stimulate healing with up to a whopping 48% improvement. So either way, it’s our go-to!)

I totally understand that seaweed sounds gross. That’s why Oprah calls it ocean-veg. And like Oprah, all the finest dames are horsing into it.



The Brew

Makes 2 mugs

Carrageen is a type of Irish mossy seaweed available in loads of Irish supermarkets like Supervalu, and certainly in all good health stores.


Roughly 20g packet of Carrageen moss
3-4 cloves
2 tablespoons raw honey
1 tablespoon apple cider vinegar or fresh lemon

Optional add-ons;
1 tablespoon grated fresh ginger
Crack of black pepper
Other citrus fruits
1 teaspoon minced turmeric root, or dried turmeric


1. Soak the carrageen in water for 30 minutes to rehydrate it. Remove, discard liquid, and rinse under the cold tap. Boil the carrageen in a large saucepan with the cloves and around 750ml of fresh water. Secure a lid on it.

2. After 20-30 minutes, strain the “ocean veg” brew and allow the liquid to cool to lip temperature before stirring in the remaining ingredients and optional add-ons.

3. The brew will set like lemon curd once cooled. If (or when) this happens, gently re-heat. If your cough is particularly chesty, make several batches with added ginger zest and sip all day, with the aid of a couple of Woody Allens.


For kids:

Add extra honey, making sure it’s locally sourced. Administer by the spoon to help with their bark! A few teaspoons a day is plenty. Not suitable for babies.



Taking the hell out of healthy.

    I made this brew using some Irish sea weed that I gathered on a Burren eco tourism tour (can’t remember the names of each but i threw in a few leaves (?) of each!)). Also added a stick of lemongrass and some cardamom in the mix! Turned out great. Thanks for the recipe! Fingers it’ll be my shield to the flu epidemic that seems to be going around! 🙂

    Just received the Irish Seaweed Carrageen from your link and bemused to see on the packet that is is from Canada. Anyway I’m sure it’s roots were in Ireland. Am about to make the brew.
