The story is these biscuits became popular during WWI when wives would make these for their soldier husbands because of their firmness and since they don't go bad quickly. In the States, Golden Syrup is becoming more available. I can find it in the British section of my grocery store and just recently found it in the baking aisle. If you can't find it, you may use 2 parts light corn syrup to 1 part honey as a substitute. I'm submitting this for ZWT and am just guessing on the yield since I haven't made this yet.
