OMG. I am a complete idiot. I made this recipe over a month ago and was afraid to try it. IDIOT!!!
I had to make changes-- Lemon Juice for the Vinegar; Light Olive Oil for the Canola; and Sunflower Lecithin for the Soy.
I just ate an entire batch of Gluten Free Shortbread. Holy Moly.
Never, Never, Never buying Earth Balance or Spectrum again.
