Okay, in the past 24 hours I have learned two new things, which, to me, were like "Eureka" moments...but apparently are pretty common knowledge:
1) Flour can go rancid.
2) If you leave the pit of your avocado in the prepared guacomole, it will help prevent it from turning brown.
I have been cooking since I was 10 and never knew these two very simple, yet helpful things.
What have been your "Eureka" cooking moments?
