Costco generally packs there pork tenderloin 2 to a package, with 2 packages sold as one unit, resulting in 4 tenderloins.

Yes, I do know those packages, Peppi. That's one reason I'm confused by a "Pork loin tenderloin" package that weighs five pounds. I suspect it is a loin. Well, I guess I'll find out.

I know nothing about buying/cooking pork, but I was curious so tried to see what I could find on the 'net. From their to business sales site: This is a Costco picture of 5 lb. tenderloin (that does look like the pork tenderloins on TV), which is a two pack, like Peppi said. Here's a different picture at a grocery delivery service, which is labelled Swift Premium, and estimated at 5.35 lb.

The Costco site also has boneless pork loin, but the smallest says average size 8 lbs. The next sizes are "strap on" 12 lbs., and bone-in 10 lb. (by the case only).

This makes my guess, if this were a game, that it's the two tenderloins, but wrapped together. :D

I think Peppi is right, I think it's two packages of two tenderloins, packaged together, if that makes any sense, making a large package which contains four tenderloins.

Now I'm going to have to watch this thread, just to see what it actually is that you have! Any loin packages that I've purchased have been much larger than 5 pounds, that's even small for a "half loin" which we often get here.

It is 'pork sirloin tip roast'. It is from the back loin but a roast. Not the 'tenderloin'. (long and skinny as most everyone is familiar) I think they come in a 4 pack. Each one of the 4 packaged individually is about 2-3 lbs i think.

My local Costco started carrying it just a couple years ago, maybe 3 yrs.

Very lean like the tenderloin.

Maybe they call it different things different places. No, it is not the shoulder.

It has been well over a year but i dry rubbed, lots, about a cup, with lots of onion slices and thick citrus slices...two 'tip roast' together and into the smoker wrapped tight for a couple hours, then uncovered, low and slow, a few more.

What does the package actually say?

It's not the sirloin tip roast. The package is shaped like a loin but the meat looks darker, as far as I can tell through the thawed liquids. There are actually two labels. One says "Swift Premium Pork Tenderloin." The other label is Costco's and it says "Pork Loin Tenderloin." Is Costco trying to say it's really a loin? I have bought Swift "tenderloin" that is actually a loin roast, in a supermarket. I should have noticed from the weight and size that what I grabbed from the freezer was not one of Costco's packs of two tenderloins.

I think folks are pointing out that you might possibly have four tenderloins in the package, at around a pound each.

That's possible. Or five or six, at that weight. The usual Costco four-tenderloin purchase, though, is what Peppi described: a separable double pack, each of which contains two tenderloins.

Don't keep us in suspense! Open it up and tell us please.

It's back in the freezer. To be continued....

"Pork Loin Tenderloin"

Sounds like a whole pork loin mislabeled by adding the word tenderloin. Mind you a pork loin "roast" can still tave the tenderloin portion attached. Normally the tenderloin is separated from the loin. Bets that what you have. Apork loin with the tenderloin portion still attached

Ha, then the label wouldn't be contradicting itself. This is boneless, though, so the loin and tenderloin would have to be separated by the boning and then repackaged together. I've never seen that, but maybe it exists.

Weird. Have not been to Costco since about this time last year...on the list for errands tomorrow. Now i want some pork loin.
