Preheat oven to 425 degrees F.
In a medium-sized mixing bowl, combine:
3/4 cup all-purpose flour
1/2 tsp. salt
1 tsp. cream of tartar
1 1/4 cups rolled oats (quick or regular; it doesn't matter much)
1/2 tsp. baking soda
1 Tbsp. packed brown sugar
Cut in 1/4 cup vegetable shortening or butter.
Stir in 1/2 cup milk.
Pat out the resulting sticky mess on a floured board, making a disk about 1/2 inch thick. Cut into wedges, as many or as few as you please, but 8 is probably a reasonable average. Bake on a greased or silicone-matted cookie sheet for . . . well, the recipe says 12-15 minutes, but mine are always done in 10. (However, my oven is old and a little overzealous.)
Off to work now. Mondays should be banned, I say.
