These are called soda biscuits and would be like the scones we make today in England. The recipe is simple:
2 cups white flour
1 tsp salt
1 tsp baking soda
1 cup buttermilk
3 tbsp. dripping
Mix dry, work in fat, add buttermilk. Do not mix too much, but blend enough to make a ball of dough.
Roll and using a mug cut out circles of dough
Place on a baking tray and bake at 210 degrees centigrade for 12 minutes.
We boiled up some blackberries, which jammed themselves without any additional pectin! We had this blackberry jam with our just baked, still warm biscuits.
