The English style of short rib is pretty much always available at most regular grocery stores that I go to, though some are thicker than those pictured in the link. Dominicks had them on sale last week for 2.49/lb, which is more than other places mentioned here, but its not like buying tenderloin. Like all Dominicks meat, you need to be very selective to get the best packages. Sunset Foods up here always has them too, but usually for 3.99-4.99/lb. I made my simplest preparation yet, and it turned out great. After browning the ribs in my dutch oven, I sauteed some onions and added 2 cans of beef broth and a bottle of a cheap Anjou red, as well as a bunch of dried porcini. I reduced that down quite a bit and added back the ribs and oven braised them for 2 1/2 hours with the lid on, and 1/2 hour with the lid off. The only seasoning was salt and pepper. No other herbs or spices, not even garlic. I had to add some water as it cooked, and ended up with a delicious thick sauce after spooning off most of the fat. Served over polenta with sauteed greens (chard and arugula), even the 7 year-olds liked it.
