Ive got an old cuisinart from the 90s that is pretty much exactly a 1/2 scale model of a robocoupe with a 2 cup bain. Love that and my stick blender.

Fave commercial appliances? The heated robocoupe, (that could be a chilled in the freezer or maintain a hot temp electronically) that could whip and aerate sauces at temp, like holandaises and chocolate sauces, even make singlenservings of sorbet ala minute.

Tha and a bakers oven i had when I was working on the size of a mountain. It had humidity and pressure controls, allowing me to simulate baking at anywhere between -2 mile below to 5 miles above sea level. Raising the altitude all the way up and running high humidity for like 20 mins made a perfect creme brule.

Setting it to 4 miles high meant a water boiling point of ~160°f, so mixed with a high humidity, I could 'boil the water out, without drying it out and barely cooking the egg.
