Heat Dutch oven in coals. To prevent the pan containing the biscuits from touching the bottom of the Dutch oven, put three small flat rocks on the oven bottom. To test for heat, place a few drops of water on bottom of oven. The oven and lid must be quite hot for proper baking.
Mix Bisquick and water with fork until dough is of a soft consistency. Spoon dough into cake pan by spoonsful. Place the pan of biscuits on the rocks in the hot Dutch oven. Cover. Dutch oven should be placed on small amount of coals, and lid covered with coals and hot ashes. Bake about 10 minutes.
