My mom used to make beef barley soup from the leftover Christmas prime rib bones too.
Thanks for the memories. Actually, I've never cooked prime rib!
I have an elderly neighbor, who is also one of our gardeners, who is recovering from a stroke and needs a hand a times. Her refrigerator went out this week and this morning I transferred her freezer's contents to my chest freezer while she looks for a replacement. Good timing, since my holiday meals are over and I have room. There is a 6-lb. prime rib in the mix. Do you think she'd notice?
(Yes, she would. She's sharp as a tack! Damn.)
