Step 1Prepare coals in a fire pit or grill. The coals will be ready when they have all caught fire and are glowing a rich red.
Step 2While the coals are heating, mix the flour, baking powder, baking soda and salt in a medium bowl. With a fork, cut in the bacon fat until the mixture resembles small peas. Stir in the buttermilk until thoroughly combined, and knead for 1 minute.
Step 3Using floured hands, divide the dough into six pieces. Mound dough over the tip of each of six sturdy sticks, and spread the dough over the tip (resembling a cattail), so that it is about 4 to 5 inches in length and 1-inch in diameter.
Step 4When the coals are glowing red, spread them in the pit or grill. Place the prepared sticks 4 to 5 inches over a hot fire, turning for even cooking, and cooking until the outside of each biscuit turns golden-brown and the inside is fluffy, 8 to 10 minutes. The biscuits should slide easily off the sticks when done. If the outside is browning too quickly, move the stick a little farther from the heat; if the biscuits are taking too long to cook, move them a little closer. Serve with butter, maple syrup, jam or honey.
