Favourite implement would be the big chef's knife, which I use for everything except bread and tomatoes. I'm definitely at one with that knife. It gives that onion-dicin' notion of competence, utterly unlike the feeling I get when I try to carve a cooked animal. I inherited a nightmare carving gene from my father, and no knife will fix that.
Favourite gadget...the kitchen has no room for gadgets, it barely has room for a cook. The one thing that has honestly improved my quality of life in the last few months has been the Schwartz "twiste and taste" disposable pepper mill, which makes me feel like I've got something on the spice rack that has super-powers.
