Seaweed Pie (not what you think)
To be honest the west coast of PEI (Prince Edward Island) is not that exciting. When Lonely Planet recommended "stop into Seaweed Cafe that serves a special seaweed pie" we could hardly contain our enthusiasm.
The reality was not exactly what we were expecting (Home made sponge cake covered with a creamy filling thickened with Irish Moss extract and garnished with cream and fresh fruit salad).
Or as Wikipedia puts it "Carrageenans or carrageenins are a family of linear sulfated polysaccharides that are extracted from red seaweeds. There are several varieties of carrageen used in cooking and baking. Kappa-carrageenan is used mostly in breading and batter due to its gelling nature. Lambda carrageenan is a non-gelling variety that assists in binding, retaining moisture, and in contributing to viscosity in sweet doughs. Iota carrageenan is used primarily in fruit applications and requires calcium ions to develop a heat-reversible and flexible gel." Yummy!
