I waited for the better part of a decade for sous vide equipment to become cheap enough for me to get into.
The verdict is that sous vide with a cast iron pan sear to finish is definitely the best way to cook chicken breasts. I’m basically trying different proteins each week. Last week was chicken, and this week is pork. The main issue I have with sous vide is the plastic waste it generates. Also, the cheapo Chinese unit I bought requires a press for each tenth of a degree or minute when setting temp/time, which means I’ve already pressed the buttons about a thousand times, as the pulled pork I did the other day had to be set for twelve hours LOLOL. The unit was around forty bucks, so I guess usability testing wasn’t a high priority for the manufacturer. It does work, it’s just unnecessarily annoying.
