Spareribs so long to pass the bend test!

[iPa64]

hi all,
I followed Meathead'recipe for spareribs (salted 2 hours before, Memphis rub, ect...).
Temperature was always between 225°F - 235°F, so I expected to pass the bend test after about 5 hours, but first cracks occurs only after 6h30. We ate them, that was interesting but I think that could be better with at least 30 minutes more! Why so long?
I noticed, that during about 5 hours, the surface of the meat was dry (mate), then after about 5h45-6h00 meat began to be shiny and "wet", maybe connectives tissues and fat began only at this time to melt ?
Thanks for your advice

Did you try to check internal temperature? ... (not easy with ribs ... but possible) ... The fat and collagen won't render until it gets and stays above 190 deg. F for a while.

[iPa64]

Yes I did, but result was different each times I tried!
Sometimes 190 (never more) sometimes a lot less!

Man that's a sweet set up you got going on with that gasser! I'm loving that. As for the ribs. All I got is. Do it again. : /

that prob looks wicked close to the meat btw. Not sure if that has anything to do with it at all.

If you cook them @ 225 C for 6 hrs then they were over cook because that would be 435 F.

Probe was at about 1.5 inch, I need to find a wider grate.
Yes I will try again and begin early, expecting about 7 hours to get the graal.
Thanks

Good catch DW. I missed that. iPa is your op correct. You cook at 225c not f ?

[iPa64]

Oups sorry, yes I mean 225°F

They look like St. Louis which routinely take me at least 6 hours @ 225. Anothing less without wrapping usually winds up less than my goal. In the future you probably should plan on a minimum of 6 hours.

Yep

If you find the ribs cooking slowly and are pressed for time, you can safely take the temp up to at least 275*. PBC users cook in that range all the time.

I'm usually 7hrs for larger racks. I've had some take 9. The 3-5hrs things is for small small racks.

[iPa64]

Yes maybe it's not the same cut here.
Here a picture of the slab before I cut rib tips.
