These bags are great! We use them all the time to cook a whole chicken. The bag is a bit big so we just trim off the extra (they used to sell medium-sized ones which fit better). The chicken ALWAYS comes out fantastic—juicy, soft and tender.
It is a toss up. I used it for ham and I found the bag stuck to the ham a little.
These are awesome to cook with, the meat is so tender and juicy and all the flavours are trapped in,
