Dr. Jessica Muhlin presented “Sensational Seaweeds” on Friday, Nov. 3, at the Witherle Library in Castine. Her talk explored the natural history as well as the uses of marine macroalgae, both historically and currently, and included a sampling of some foods containing seaweed and cookbooks encouraging the use of seaweed in cooking. The following week, on Wednesday, Nov. 8, Professor Muhlin hosted her annual “PhycoFeast” with her Botany class at the Castine Emerson town hall, embarking on a new chapter in which PhycoFeast is open to the Castine community in addition to MMA. PhycoFeast is a hands-on seaweed food workshop.
