So i decided to google this morning, and i have been just buying butts at whichever store has them on sale. Well i noticed on some youtube videos, people talk about the best part of the butt is the "money muscle" i just looked at a 5 pounder i have to do today and i noticed, there is no "grain" on the side, in fact. I think the way this thing looks, the money muscle may of been already cut off before it was sold at the store ? Is this normal? This was either a smithfield or that other vaccum sealed brand they carry. Do i need to get a sams club membership or something?
