**Can use margarine or Crisco---are best with butter! To make sour milk, add 2 ts. vinegar to the half c. milk. DO NOT use actual sour milk! Cream butter, sugar, then egg. Add soda to milk, and powder to flour. Alternat flour and milk, mixing well. Roll and cut into shapes. Bake at 180ºC or 10 mins. Cook best on airbake pan--keeps them softer and not browned looking. *This recipe was from my paternal great grandmother. She never used a recipe, just her head when making these! Are good sprinkled with sugar, and decorated. ----
