You presumably exclude non gadgets like the really sharp knife?

I'm rather fond of a broken garlic press we keep because it has a cherry stone pitter in the handle. We stone olives with it mostly.

Our potato ricer gets a lot of work.

The magimix less, but for making a lot of mirpoix in a hurry, or pizza dough, or blitzing herbs for salsa verde its hard to go past.

The blender gets most work. Hummus.

But really? The $26 salad spinner. Major upsides to clean dry salad leaves and herbs.
