Okay, I have to resurrect this thread. I'm completely sold on this little device. They are $19-$20 at Amazon, free delivery with Prime membership.
I was looking at meat tenderizers when I came across the Jaccard. It got good reviews on Amazon and here at SMF. My wife said "heck, for $20 buy it." When it arrived she confiscated it and wrapped it for Christmas.
Now, we've been less than happy with steaks from Costco for several years. They used to be awesome but the ones we can get now at our local Costco can best be described as "tight." Not tough really, but definitely not melt-in-your-mouth tender. Way too much chewing. We swore off steaks from them and paid higher prices at my local grocer when we were in the mood for ribeyes, our favorite cut.
The first place I went after getting the Jaccard was Costco and picked up a 3-pack of Choice grade ribeyes for $9.99/lb. They were about 1 1/4" thick. Even raw they felt "tight," just like I remembered. I worked each one over 4 times with the Jaccard. They spread out and became about a quarter sized larger than they were before I started tenderizing them. I seasoned the meat then threw them on the Kettle for my usual cook time, 6 minutes a side.
They cooked faster and were a little more done than I care for; medium instead of medium rare. While resting there was definitely more fluid loss but OMG they were melt-in-your-mouth tender! We put the leftovers in the fridge and the meat reabsorbed all the jus.
I'm sold on this little device and can't wait to use it again on just about anything. If you want a cheap way to tenderize meat that doesn't involved beating the crap out of it with a meat hammer, the Jaccard is it! Dishwasher safe too.
