Gag!

We used to buy this product and customize it, was great.
Over the last year, we have tried it 5 times and Gag! it always comes out terrible. We follow the instructions to the T and have a good even heat oven. We use a pizza pan, we dont add flower to our hands, while making. It always tastes bitter and real bad. No one will eat it in the home, not even the dog. I keep thinking I am doing it wrong but every time the same, Gag ? Is there a hidden step, or something everyone else knows about? I miss the old kits that worked great and tasted Good.
