Notes

  • Weigh your ingredients. Measuring by weight is much more accurate than by volume (with tablespoons and cups)
  • Both sourdough discard and active sourdough starter will work for this recipe. 
  • This recipe was developed using salted butter, add ¼ to ½ teaspoon salt to your cookie dough if you choose to use unsalted butter.
  • If you use any of my homemade preserves recipes, be sure to strain them first.
  • High altitude, bake for 18 to 20 minutes.
