Seaweed Workshops

Primary tabs

N.H. Sea Grant and UNH Cooperative Extension are working to help people in New Hampshire understand: 
1) the benefits of and possibilities offered by the use of seaweeds in cooking

Seaweed as Food
N.H. Sea Grant has partnered with UNH Cooperative Extension, Maine Sea Grant and Stages at One Washington (Dover, NH) to develop events for people to learn how to handle, identify and prepare several different species of sea vegetables. Recent workshops have featured an introduction to the types of seaweeds found on the NH coast and demonstrations of how to create creative and healthy dishes using sea vegetables (what seaweed is called once prepared) as an ingredient.

Jump on the seaweed bandwagon!

Attend our Seaweed Mania! events and learn about the health benefits of seaweed and how to incorporate it in your cooking. Don't know where to buy seaweed? No problem! We have a workshop that shows you the best, local source for seaweed foraging.

Known as 'sea vegetables' or 'ocean herbs,' seaweeds (marine macro algae) are undoubtedly the ocean's most versatile and sustainable resource. Seaweeds are used the world over for food, extracts, personal care products, health products, artistic creations, textiles, and soon, possibly, as alternative fuel!

Join us "In the Kitchen" at Stages at One Washington as we gather for a unique bean to bar experience - When Chocolate Meets Seaweed. Guided by Chef Evan Hennessey of Stages at One Washington and Enna Grazier of Enna Chocolate, a local gourmet chocolatier, we'll explore the pairings of various seaweed and grades of chocolate that will surely pique your sweet and salty cravings.
