Anyone here ever watch the anime "Food Wars"?
I personally love Japanese food so I enjoy watching it every now and then. They had this one scene where they make a "Claiapin Don" and I thought it looked really good.
The idea is that you chop onions up into fine pieces and then let a piece of steak pratically drown in the onions on both sides in order to tenderize the meat. I'd recommend letting it sit for about 45 minutes. Then you scrape the onions off and caramelize them
I use a cast iron, do whatever works best for you after that you take out the onions and put salt and pepper on the steak and grill it off in the same pan. What I like doing is putting just a splash of red wine in the pan before I throw the steak in there for more flavor, and it also has the added benefit of further tenderizing the meat. When the steak is done, you put the onions back in there with a splash of soy sauce and cook them even further, and you top the steak off with a big mountain of onions.
You can also do it like the anime does and add it to a rice bowl with pickled plum mixed in. I did it with lamb chop one time and it was so good. And the onion tenderizing method really does save a cheap ass piece of meat.
