New circulator owner, three steak cooks in, and I have a grey band problem. Strip steaks at 129°F (54°C) for 2 hours, out of the bag they look incredible, wall to wall pink. Patted them dry with paper towels, cast iron on high for a good while, seared about 90 seconds a side plus a bit on the edges.
Result: crust is honestly just okay, and there's a 5mm grey band under it on both sides. Which is basically the thing I bought this machine to escape. So what's the move, hotter pan? Less time? Do I genuinely need to buy a torch like every video says? I was promised edge to edge and I want what I was promised.
Alright, barbecue guy perspective, because searing is just a very short cook and the same rules apply.
Dry is 90% of your problem. "Patted dry" is not dry, the surface is still wet enough that your first 30-45 seconds of sear time is spent boiling water instead of browning meat, and all that time the heat is creeping inward making grey. Bag to wire rack in the fridge, uncovered, 30-40 minutes while your pan heats. Kills two birds: surface dries properly AND the outer few millimetres cool down, so the band has further to travel before it greys anything.
Then do the math on your current routine. 90 seconds a side twice, plus edges, that's four-plus minutes of cook time on a steak that was already perfectly cooked. Thats your band right there, nothing mysterious about it. Ripping hot pan, oil the steak not the pan, 45-60 seconds a side ONCE, press it down for contact, out. It'll feel wrong stopping that early. Stop that early.
Torch plus pan together ended this problem for me, torch works the top while the pan does the bottom, done in half the time so the heat never gets a chance to travel. Not essential like the videos claim, but its a fun way to solve it.
#4March 22, 2026, 2:37 pm This exact grey band is personal for me, chasing it is half the reason this site exists, my pre-sous-vide steaks were grey all the way through and I was not about to accept a band of it back as a souvenir.
What fixed mine, in order of how much difference each made: actually drying the surface (Mike's fridge rack trick, it changed everything), cutting my total sear time roughly in half, and getting the pan properly hot before the steak touches it rather than "probably hot enough". I wrote the whole sequence up, including the torch question (nice, not necessary) and why a steak from the bath barely needs to rest: how to sear after sous vide.
Post your next result in this thread, I love a before and after.
Reporting back: fridge rack for 35 minutes, screaming hot pan, 50 seconds a side and I made myself stop. Band is nearly gone, maybe 1-2mm, and the crust was better despite the shorter time which makes no sense to me but I'm not arguing with it. Upgrading my complaint from "annoyed" to "fussy". Thanks all.
This one's closed: 60 days went by with no new replies. Cook times age fine, but safety answers deserve a fresh look, so check the current charts or ask a qualified professional rather than trusting a dusty thread.
