The method is very straight forward. Egg white is used to bind the toasted sesame seeds. By combining with sugar, flour and butter, a mixture is formed. When the mixture is spread out into a thin layer and baked, it is “transformed” into a crunchy crisp. The tricky part is to make sure each layer is spread thinly and evenly, which means no overlapping of sesame seeds. A fork and a little patience are all you need to achieve that.
