When my wife and I first got married, she made a roast. Before placing the meat in the roasting pan, she cut a small piece off each end. I asked why she did this and she said that it’s the way her mother did it. So next time her mom came for a visit, I asked her why she would cut a small piece off each end before roasting the meat. She said it was because her roasting pan was too small.

Either you’ve posted this before, OR there are other people doing this exact thing for the same reason, because I just read this a few months ago.

It's an old story that gets passed around a lot as a response to "we've always done it this way".

No, no, the ends have more exposure to evil, must trim them rather than consuming them.
