Does anyone know if it's safe to put the food in the water bath before it hits the target temperature? It's just that I can be so busy at times and I need to be on the go, so I don't really have time to wait for the water to preheat and I thought that maybe, before leaving, I could have the SV setup (bagged food, water bath, Joule) prepared (i.e. have it heating to target temp.) and just hit the start button when the target temp. is attained via Wi-Fi.
