The importance of why?
Often, questions starting with “why” can be construed as being confrontational, but asked with a genuine interest in learning the reason behind something it is possible that we can stop “wasting a lot of good meat:”
The grandmother stared at her daughter in amazement.
Every time you cook a pot roast you cut a 1/4 inch off the ends?
Every single time?
Yes!
She answered her mother.
Every - single - time, just like you showed me.
Honey, all I can say is you been wasting a lot of good meat over the years. The only time I ever cut the ends off the roast is if it’s too big for the pan!
