I don't think it is a mandatory item to have (more)
but I have fun with gadgets. From crockpots to sous-vide, to pressure cookers, I like to experiment and stretch my horizons
I don't think one NEEDS to have a sous-vide, but for instance, for flatiron steaks, sous-vide makes it perfect and no other method comes even close. So if I buy a flatiron steak, I know it will be cooked sous vide, every single time.
it is also very convenient because I can set it up at lunch time and have just a few minutes of final touches before dinner time -
But I agree - one can cook anything without it. I just happen to have fun with it, and well.. that's enough for me smileys/wink.gif
