On my monthly Costco shop, I always buy a package of flap meat. It makes the best steak for the best price ($8-9 per pound - used to be $6!). It's a splurge but we get two "fancy" meals out of our $25 purchase. It comes in two pieces, so I put them in the freezer individually in gallon bags (I usually thaw by submersing the meat - still in the sealed bag - in a bowl of hot water for about twenty minutes).
To make this delicious steak, I heat up butter (or bacon fat) in our cast iron pan on medium high, turn on the fan, and cook it on one side for 5-7 minutes. I flip it and repeat. Sometimes I have to flip it one more time to get it perfectly medium to medium rare. I let it sit for a few minutes before slicing against the grain.
If I am cooking onions (usually red), I cook them in the (greased) pan for about 5-10 minutes and then add the steak, cooking them both together until the onions are nicely charred (I take them out before the steak). Sometimes I add mushrooms, but if I do that I usually cook it all before I make the steak, so as not to overcrowd the pan and because mushrooms are liquidy.
This is one of our favorite family dinners - steak, mashed potatoes, and salad (the kids don't have the onions and blue cheese - more for us!).
My husband asked me to write down the beef barley soup I concocted yesterday, since he said it was "restaurant quality," so here goes (read it all the way through before preparing):
Brown 1lb chunks of stew meat in bacon fat, stir in chopped onion, celery, and carrots, about a cup of each.
After a few minutes, add 4 cups beef stock and 4 cups chicken stock, a half pound more of stew meat (not browned), 2 bay leaves, 1 T Worcestershire sauce, 1 T tamari (or soy sauce), 1 T Trader Joe's umami paste (optional - can use tomato paste), 1/2 t seasoning salt, 1/2 t garlic salt, 1 t chicken bouillon concentrate (because the cartons of stock from Trader Joe's aren't as flavorful, though healthier), and top with a cup of sliced mushrooms.
I did all this in my instant pot. Turn it to the slow cook setting on normal for two hours. Turn it up to high for another hour. Add Trader Joe's quick cooking barley for the last 20 minutes.
