Preheat your oven to 425 degrees F (220 degrees C/ Gas Mark 7)
Whisk the flour, baking powder, baking soda, and salt together in a large mixing bowl. Once they’re thoroughly combined, whisk in the frozen grated butter.
2 cups all purpose flour, 1 tablespoon baking powder, ½ teaspoon baking soda, ¼ teaspoon kosher salt, 6 tablespoon salted butter
Pour in the honey and the buttermilk, stir with a silicone spatula until the dough is thick and kind of shaggy, with all the liquid absorbed.
2 tablespoon honey, 1 cup buttermilk
Transfer your biscuit dough onto a work surface with a light dusting of flour, flatten and fold the dough with your hands into a rectangle. It's alright if the dough seems like it's just a little too dry, as you work the dough the buttermilk will moisten the dry flour mixture.
Fold the dough by thirds onto itself, then flatten into a rectangle again using your hands. Repeat this at least 3 more times, flattening the dough into a ½-inch thick rectangle, and folding by thirds to build the flaky layers in your biscuits.
Optional step: wrap the folded dough with plastic wrap and set in the fridge or freezer to chill for 5 to 10 minutes. This will ensure you have cold butter that'll keep your dough laminated and flaky, like when making croissants.
Unwrap the biscuit dough if you chilled it, and flatten the dough to 1 inch thick. Dip a 2-inch diameter biscuit cutter into a little excess flour and cut biscuits using an up and down motion. Never twist, that will seal up the edges.
Mix together the melted butter and honey. Brush the mixture of melted salted butter and honey onto the tops of the biscuits, so they'll be golden brown when ready.
2 tablespoon melted salted butter , 1 teaspoon honey
Place the biscuits onto the hot cast iron skillet quickly in the oven and bake for 13-15 minutes or until the tops are golden.
