This recipe called Rock Cakes seems very similar to one that Gram had called Rocks and another I have called Nuggets. All of these recipes vary slightly from one another, but appear to produce a very similar cookie. I have not tried any of these yet, but I believe they would be a firm and not too sweet cookie, good with tea or coffee.
Put into a basin 1 lb flour, 1/4 lb butter, a pinch salt. Break the butter into the flour, in pieces the size of a pea. Add to this 1/4 lb sugar. Mix these well to-gether, add a teaspoonful baking powder, 1/2 teaspoon ground cinnamon, 1/4 lb cleaned currants, 1 oz candied peel minced finely, 2 eggs well beaten, with enough milk to make a stiff dough. Mix well to-gether with a fork. Drop some pieces on to a greased baking tin. Place in a quick oven & bake for about 20 minutes.
