So I stopped buying flats a while ago. While they are more appropriately sized for my family, they just never come out the same as a whole packer. So imagine my dismay as I pulled a 5 1/2 lb flat out of the freezer the other day. I was so ready to get out of the grocery store last month tha I didn't even look at the label where it said "Brisket Flat Cut." Doh! In my defense, it was about twice as big as any flat I've ever seen but still I was feeling kinda dumb. Oh well, might as well cook the dang thing.
