  1. I tried another recipe, wasting 3 sticks of butter, and then found this. YAY! Your recipe worked great! I was careful not to get it to the “ghee” stage, where the dark dust forms on the bottom of the pan. EXCELLENT!

  2. Almost followed this recipe but only had liquid Stevie handy. Took advice not to undercook. Mine seemed watery and after letting it set up over an hour the color was no translucent but cloudy. Where did I messed up?

    • Hi Lisa,

      The problems you have are caused by swapping a granulated sweetener for a liquid one. Liquid and granulated are not interchangeable in a lot of recipes, and this is one of them. I hope you try it again with a granulated sweetener, I’m sure it will turn out perfectly!
