But I have a question about how and if meat is aged in Africa and Argentina.
I've heard the same about Africa; they hang it one day at room temperature then cool it and cut it. ( probably illegal here, but maybe it lets the meat relax or something?)
From the African, South that is, horse's mouth!
The current steak I am enjoying was harvested on 24 November and has been wet aged in a vacuum pack, the whole cut, at refrigerator temperature. Breed unknown, but slight marbling and a good layer of fat. We call it sirloin here but I think it is called strip steak in the USA. It is the eye muscle as measured in the EMA scan on an animal.
I cut inch thick slices, as and when I need them, baste them for two hours at room temperature in a commercially available basting sauce and cook them for about two to three minutes per side, after sealing both sides to lock in the juices.
The flip side of this is what you describe. Because of limited availability of refrigeration in small rural towns and villages, I have seen meat being sold on the sidewalk, in the open, with the vendor sitting waving a leafy branch over the meat to keep the flies away! As you can imagine, as the day wears on the enthusiasm wanes and the pest control becomes less fanatical. The moral of the story in this situation must surely be that you should buy your meat from a fairly whole carcass, first thing in the morning, if you shop at a street vendor in Africa!
