I'm sorry that you are feeling bad. Your mom is wonderful and you are so lucky to have such a close relationship with her.
I can't find it now, but you mentioned having a
fresh chicken dinner on Sunday. To avoid tough meat, you need to age chicken (similar to hanging beef). Here are Gina Bisco's recommendations:
"After processing, for best meat texture, chickens should be chilled and aged before cooking. Most sources recommend chilling and aging chickens for 24 hours, and up to 3 days before freezing. I think aging at least 24 hours improves the texture, and that older chickens are better with longer aging, up to perhaps 5 days in the refrigerator for fowl. The properly aged bird should retain a very fresh clean smell with no hint of taint. I've read that chickens that are to be frozen need not be aged first if they will remain at least a month in the freezer. However, that advice may have been based on industrial meat lines, butchered very young. For historic breed chickens butchered at 12 weeks or older, freezer aging may not be enough. If a chicken was not aged in the fridge for at least 24 hours before freezing, then after thawing I usually will allow it another day or more to age in the fridge, before cooking."
I use an ice chest, packed with ice, to age multiple chickens, for 1 to 3 days.
