LA style cut beef short ribs are cut across the bone thinly, so each piece on the grill is a long, thin strip, with 3 bone sections in it. This is also known as a “flanken” cut, but flanken is usually too thick, about ½ inch. LA style should be 1/8 to ¼ inch thick. You can ask your butcher for this, or buy it at a Korean grocery store.
My Hmart in Cherry Hill NJ charges $22.00 per pound for these. I didn’t know until recently that the shoprite near me sells these, cut very thick. I spoke to the meat cutter and they cut to order for me. $9.99 per pound.
I just noticed that in your photo, the LA galbi was only $6.99/lb. Oh my god, this costs $9.99 at H-Mart in K-Town, NYC. The M2M grocery store in the East Village sells this for $8.99/lb. Where do you buy your LA galbi in NYC, Maangchi?
