We all know about the use of seaweed in making sushi, but seaweed growers are hoping to claim a much broader sector of the food market. An Israeli company is offering new 'gourmet seaweed' products. The blurb reads: "Our seaweed lines are perfectly suited to the modern, busy European lifestyle as they are presented in convenient, easy-to-use formats and bring a fresh, sea-breeze aroma..." the company goes on to suggest seaweed can be added to flavour pizza sauces! But the most unusual use of seaweed as an ingredient would have to be in Seaweed Pie. Seaweed contains a gel which acts as a natural thickening agent, like gelatine. In Canada, Seaweed Pie is made by boiling the seaweed to extract the gel, adding this to sweet whipped cream, piling the mix onto a sponge cake and garnishing the top with strawberries, raspberries or blueberries. You can try the pie at the Irish Moss Centre, Miminegash, Canada. Who's going to give it a go?
