Preheat the oven to 400°F. Line a large baking sheet with parchment paper.
Using a coffee grinder or food processor, grind the oats into a flour.
In a medium mixing bowl, combine the oat flour, sorghum flour, millet flour, sugar, baking powder, cinnamon, ginger, baking soda, salt, nutmeg, and cloves. Stir until the ingredients are mixed together well.
Cut the cold ghee into the dry ingredients. This can be done using a fork and knife, with a food processor, or with your hands (if you work fast). The ghee pieces should be the size of peas. Having chunks of cold butter in the dough results in the traditional scone texture.
In a small mixing bowl, beat together the egg, pumpkin, and water.
Stir the egg mixture into the flour mixture until the dough starts to come together.
Turn the dough out onto a floured surface or a silicone mat and kneed 6 times.
Shape the dough into a 6 – 7 inch circle. It should be about an inch tall. Cut it into six pieces, like a pizza. Transfer the scones to the baking sheet.
Bake for 18 – 22 minutes. The scones should be firm and starting to brown slightly.
Transfer the scones to a cooling rack. Once completely cooled, store in an air tight container.
Put ghee in the refrigerator a day before you plan to make these scones. The dough can be made and shaped into scones ahead of time, and then frozen. Place the unbaked scones on a parchment lined baking sheet in the freezer for 45 minutes. Then, transfer them to a freezer bag. To bake frozen scones, place them on a parchment lined baking sheet and bake them at 400°F, adding 2-4 minutes to the baking time.
