WARNING The amount of milk and liquid butter to flour ratio makes a batter, not dough. Reduce the milk to only 1 cup and optionally add an egg. <br/><br/>If you do this it is amazingly good especially with Cheese or Preserves.<br/><br/>Once again it is way too much liquid to make dough. I tried it with 2 cups of buttermilk and then tried to add more flour to it to smooth it out. Now I have a big bowl of wasted slop in my fridge that I am trying to figure out what to do with. I then started from scratch with 1 cup milk and 1 egg. The dough turned out perfect. When baked it puffed up correctly and tastes amazing. I almost suspect someone got the amount of liquid wrong in this recipe I only wish I caught the mistake sooner!

Ingredients Nutrition

  • 1 pint buttermilk
  • 12 cup sugar
  • 12 cup butter (not spread or tub product) or 12 cup other shortening, melted (not spread or tub product)
  • 1 teaspoon salt
  • 78 teaspoon baking soda
  • 3 12 cups rye flour, coarsely ground (you may need to adjust the quantity, depending on the texture of the dough)


  1. Preheat oven to 425F and lightly grease a cookie sheet.
  2. Place the dry ingredients into a bowl; add all the melted butter and the buttermilk a cup at a time (you're looking for a thick dough).
  3. Shape into 24 balls; dip into flour.
  4. Roll out very thin and prick the dough evenly all over with a fork.
  5. Bake until brown, about 15 minutes.
