Finally ordered one of the 48-blade Jaccard tenderizers from Amazon.
I was wondering if there are any key tips, tricks, or just general things to be aware of when using one. I've read the half-page on them in MC@H, including the warnings about what it does to the sterility of the meat - but reading reviews on Amazon and so on a couple of people mentioned other problems, like it making it harder to do steak rare but seared on the outside, and so on. Plus I myself am wondering about some of the practical elements - do I risk damaging my chopping board? If I'm tenderizing something with skin on, should I avoid pushing the blades through from the side? Etc...
