Preheat oven to 425°F (220°C). Line a baking sheet or preheat a cast iron skillet.
In a large bowl, whisk together flour, baking powder, baking soda, and salt.
Cut in cold butter or lard until the mixture resembles coarse crumbs.
Stir in honey or maple syrup if using.
Add buttermilk a little at a time until a soft dough forms.
Let the dough rest for 10 minutes to fully hydrate the fresh milled flour.
Gently pat dough to ¾-inch thickness. Fold once or twice for flaky layers, then cut biscuits.
Place biscuits close together on the pan for soft sides or spaced apart for crisp edges.
Bake 12–15 minutes until risen and golden.
Brush tops with melted butter if desired and serve warm.
