Here is a Baking tip for you, that I had to find out the hard way!
Last year my daughter and I were doing our Holiday baking and making my Italian cutout cookie recipe, we tasted one and they were awful!!
It tasted like I had put a cup of salt in them....so we threw that batch away and started over. Well the second batch tasted the same way, needless to say after the third time I went one by one and checked each ingredient I used. The culprit was expired Baking Powder!,,,I felt bad wasted all of those ingredients,,,It was very frustrating!.....So now I always check the dates on all of the ingredients I am using.....Lesson Learned!!
