At work, part of my job is to make sure we use fresh ingredients. Everything is labeled with the date it was opened, and when it expires. At home, I don't pay attention with the same detail. This morning I made hockey pucks. They were supposed to be biscuits, but they were flat and very dense. After such a disaster, I decided to check labels. I had a trifecta of expired ingredients. The flour was about 3 months past expiration, the baking powder was 6 months, and the baking soda was only 10 years older than it needed to be. A quick trip to the store and new ingredients, made a huge difference. Check your expiration dates, to keep making great food, not hockey pucks.
