My cousin did something similar. She liked to mix cinnamon and sugar and put it in toast. One day she was making it and grabbed an unlabeled container of what she thought was sugar, but turned out to be salt. The look on her face when she took the first bite was hilarious!This one happened recently actually,
So, we were having french toast for breakfast (my favorite), and I went to get the powdered sugar out of the pantry. I grabbed a small container of some white powdery stuff that I assumed was powdered sugar. And, being the sugar craving creature that I am, I opened it, stuck my finger in and licked it. I can still taste it! It was not the delicious sugar I was expecting, but baking powder instead! It was horrible! I'm glad I didn't dump it all over the french toast though.
