I had decided to make cookies for people at work. I used the "Country Save" sugar cookie mix that I had used previously. Unfortunately, I decided to use some vegan butter that someone gave me rather than regular butter. Somehow the cookies got that potatoes-ish flavor many of my vegan/gluten free cookies get. :/ Sad.
So let this be a lesson: Don't experiment with different types of butter (Or other ingredients) when you are planning on serving what you are making to other people.
