I did a trial with some stewing steak, one I did nothing with,the other I used the jaccard on then cooked both sous viide at 60C for 4 hours with a small of gorgonzola in each bag, the jaccarded steak was preferable and softer than the non jaccarded steak. Interestingly the small amount, and I mean a smear, of blue cheese really brought out the beef flavor and was eaten even by a guest who will not eat any form of cheese.
