These Drop Biscuits are the easiest biscuits and so fluffy! No kneading the dough or cutting biscuits needed.
Line baking sheet with parchment paper or silicone baking mat. Set aside. Preheat oven to 400 degrees F.
In a small measuring cup beat well the egg. Grab butter and milk from the fridge. Pour 1/2 c of milk to the cup with egg and stir well. (No need to look for another measuring cup; the beaten egg should measure about 1/4 c so pour enough milk to make 3/4 c liquid.)
Grate the butter straight over the dry ingredients. Cut in with pastry cutter until the mixture resembles coarse crumbs. Add the egg and milk mixture and stir until all is moistened. Drizzle the lemon juice over the dough and give it a few stirs.
Drop the dough onto prepared baking sheet by heaping tablespoons. Bake for 18 to 20 minutes or until the biscuits just start to brown on top. Cool on the sheet for 2 minutes, then transfer onto a wire rack or cutting board to cool completely.
