Test Kitchen Tips

  • Salted butter and a splash of extract (try almond!) make these extra flavorful.
  • If you like your treats on the sweeter end of the spectrum, add a pinch of coarse sugar to the tops of these light and airy cookies.
  • Why cream of tartar? Baking soda needs an acidic ingredient to create the gas bubbles that make baked goods rise and lighten. Cream of tartar (aka tartaric acid) provides that in this recipe. Yay, chemistry!
