Food Safety and Temperature Limits for Long Cooks (18-24h)?
Hi everyone!
I got 3 beef steaks, but I separated them by removing the lid, the highlighted part. I vacuum-sealed them and froze them for a week. Now I'd like to cook them.
I read that they're tougher than the rest of the cut, so I was thinking of doing a long sous vide cooking and then finishing them over the coals. I've never cooked meat for longer than 3-4 hours and wanted some clarification regarding food safety.
First of all, is there a minimum temperature below which long cooking is not recommended? I usually cook meat at 125-130 F (52-54 C). I'm worried that holding the meat at 125 for a long time could encourage bacterial growth and ruin the meat.
Also, do you think cooking this cut for 18-24 hours is enough to achieve good results? Is it too much?
Thanks for your help!
