One of the many things I appreciate about Joule is it's ability to tenderize cheaper cuts of meat. I tried it yesterday with a confusing result.
I cut a three pound eye round roast into four 12 oz steaks. The steaks were about 2" thick. Before seasoning and pre searing, I used a Mercier manual meat tenderizer. For those unfamiliar with this device, it consists of 56 needles which perforate your meat. Since eye round is a tough cut, I set my beloved Joule for 8 hours at 132 degrees. This should have produced a steak between rare and medium rare,.
The result was a relatively tender steak. Certainly more tender than eye round cooked a conventional way. The texture reminded me of sirloin. So far so good. But the doneness was between medium and medium-well, grey with just a hint of pink! How did that happen at 132? I'm quite sure my beloved Joule didn't malfunction. Other meats I have tried have turned out as expected. Was it the Mercier meat tenderizer? Has anybody tried it? The 8 hour cooking time? Shouldn't be a problem with doneness. Texture perhaps, but not doneness.
I'm confused. Any thoughts?
