Preheat the oven to 400°F.

Stir the flour, baking soda, ascorbic acid and salt together in a mixing bowl.

Blend in the oil with a pastry cutter until the mixture is crumbly. Stir in the water until dough holds together.

Turn the dough out onto a spelt-sprinkled board and knead about 25 times.

Roll or pat the dough out until it's about 3/8" in thickness. With a spelt-dipped biscuit cutter, cut out circles and place on a parchment-lined (or ungreased) baking sheet.

Bake the biscuits for 20 to 25 minutes.
