Combine oatmeal, salt and baking soda.

Pour in the melted butter, milk, and enough water to make a stiff dough.

Turn the dough onto a floured surface and quickly knead for 30 seconds.

Roll dough to 1/4 inch thickness and cut out cakes with a 3-inch cookie cutter or glass.

Transfer to a lightly greased baking sheet and bake at 350 for 30 minutes, or until oatcakes begin to brown.

Cool on a rack and store in an airtight tin.
