Preheat oven to 400 degrees.
In a large mixing bowl, combine dry ingredients such as the flour, salt, baking powder, cream of tartar, sugar. Add the butter and mix, and then add the grated cheddar cheese. The dough should resemble coarse crumbs. Add the buttermilk and stir with a fork only until the dough follows your fork around the bowl. Dust the surface of your table with flour. Knead gently with hand 10 or 12 strokes. Do not over mix the dough or your biscuits will become flat. Roll dough out to one half inch thick (1/2 inch) Dip the biscuit cutter into flour, then cut straight down. Bake on a ungreased shiny baking sheet. Bake in oven at 400 degrees for about 30-35 minutes or until the biscuits are golden brown.
