Seaweed soda crackers

Preparation

• Preheat the oven to 175C/350F. Mix the flour, baking soda, icing sugar and salt together in a mixing bowl.
• Rub shortening into dry ingredients until mixture looks like loose crumbs. Add in egg white and combine briefly.
• Add in the dried seaweed and blend all the ingredients together with your hand.
• Place the dough between two sheets of plastic film, and roll it out into a rectangle, about 2mm thick.
• Divide it into 24 equal rectangles and prick the tops with a fork.
• Then use the back of a knife to make two vertical marks on the surface.
• Lightly brush them with egg white and then bake in the center of hot oven for 25 minutes.
