Fiona Gallagher. Played by Emmy Rossum. Fiona Gallagher. Fiona is in the difficult position of being the oldest of the Gallagher children, so most of the responsibility and child-rearing falls on her young shoulders. This young woman takes it all in stride -- she's clearly been doing it for a long time.
Take a look at a typical pancake recipe - it tends to ask for eggs and milk, i.e. protein. Pancake mix only needs water, so it will have a higher protein content than normal flower (and is probably flavoured). So you probably can't replace flour with pancake mix in a recipe and expect the same results.
You actually should throw out any pancake mix, brownie mix, cake mix, etc, immediately after the expiration date because it can grow mold that could cause a life-threatening allergic reaction.
