N.B.
I guess I thought this wouldn't be appliances ( I consider gadgets to be non motorized/electrical??)...but I am game!
My crock pot. But I am longing for a Kitchen Aid Mixer (and a fabulous kitchen to go with it! LOL)
As far as drawer type gadgets...my several Pizza Cutters I have 4 I think?)..hands down! I do home childcare..and I use them to cut EVERYTHING. Pizza..certainly..but toast, grilled cheese/any sandwich, any waffles, pancakes, quesedilla, wraps...anything canned (veg or fruit). Great for my crew of kids usually age 2 and under. (I don't serve chicken nuggets or fish sticks, but you certainly could do those foods too)...
