Preheat the oven to 450℉.
In a small cup, combine lemon juice and milk. Allow the mixture to sit for 5 minutes to develop.
In a large mixing bowl, combine flour, baking powder, sugar, salt, and cream of tartar.
Remove the butter from the freezer and cut into small pieces.
Using a pastry cutter, incorporate the butter into the flour mixture to create a sandy texture.
Pour the sour milk into the bowl and stir to combine all ingredients.
Drop the dough onto a lightly floured surface.
Roll the biscuit dough with a floured rolling pin about 3/4 to 1 inch thick.
Cut as many biscuits out of the rolled dough as possible and place in the preheated oven.
Bake for 10-12 minutes, or until the tops are browned and the biscuits have doubled in height.
Reroll any extra dough and continue cutting out biscuits until all the dough has been used.
Mix 1 tbsp of melted butter with 1 tbsp of honey in a small bowl.
Once the biscuits are finished baking, remove from the oven and brush honey butter on top of each biscuit.
Cool on a wire rack for at least 10 minutes before serving.
