Excellent looking meatloafs! I've come back around to enjoy meatloafs. Growing up, my mom's version was horrendous!! Haha. Took me a while to see there were way better versions. Yours definitely looks great!
You should also be able to tell by price. A full packer in cryovac will be less expensive per pound generally speaking, than the flat, because more butchering work has been done to the flat.
We are our own worst critics! Trust your guests and their compliments, and everyone here. :)
Great pics, thanks for sharing and it all looks spectacular. Well done!
