Tonite, I picked up a nice pork shoulder. In searching
recipes, each is calling for cooking it to a specific
temperature (~170F) and then removing it from the oven.
Would it be a bad idea to continue cooking it, or is
there no reason to do so; ie., is there not enough
collagen in the pork shoulder to require further cooking
to render it?
I cook them to temperature. I just did a couple boneless
shoulders a few days ago. Took them out of the fridge 2
hours before cook time. Rubbed them with a spice mixture
and put them into a 250F oven. Cooked them to 145, let
them rest for 20 minutes and the residual heat brought
them up to 154F.
Tender, moist. Wonderful served as sliced pork that day.
Cold sliced on sandwiches later. Also did some in wraps.
Cubed some for a salad.
And this was pork shoulder? I would have thought that,
like beef shoulder, there would be alot of connective
tissue that needed rendering by longer cooking. So there's
no collagen to dissolve in the cooking process?
(obviously, I've not cooked much pork <g>😉
There's some, but the musculature of the two critters is
very different. Pigs have much less connective tissue and
the individual muscles are smaller. There is some gristle
that runs through a small part of it, but I'm willing to
live with that to keep the meat moist and tender. And, in
any event, it can be trimmed before service if you want.
I buy boneless, skinless shoulders. Most of the surface
connective tissue is trimmed out already and just a thin
layer of fat remains. Inside, removing the bones, tendons
and ligaments means that the internal connective tissues
have been largely removed. Thin layers between muscles don't
much matter in the finished roast.
Slices cleanly. And can be sliced on my slicer paper-thin if
I want to. Cooked more, to 150F or more, the denatured
protein makes it difficult to do that. Cooked to BBQ levels
means that slices can only be done rather more thickly.
The final determinant of a sense of moistness in the meat is
the degree of doneness it's cooked to. The more cooked, the
drier. Adding water or stock to the pan won't keep the meat
more moist. Low-temp roasting can help to preserve a bit of
that moist mouthfeel by softening the collagen. The gelatin
adds what seems to be a fat mouthfeel, but without fat. I
find that if I don't either cut or cook enough out, it eats
"sticky." That's why I like to get it out up front and just
cook the meat to medium.
The other reason I like to cook it this way is the yield.
More comes out of the oven in the end than if I cooked it
either at a higher temp or to a greater degree of doneness.
I don't much like today's pork cooked to the high internal
temperatures that they did when pork was fattier. If I'm
making pulled BBQ, I'll cook it to about 195 where it begins
to fall apart all by itself, but I don't do that often.
Rather have a roast in a single piece that I can slice or
chunk for various dishes. YMMV.
