I’ve always liked chopping onions with a knife, but I actually love chopping them with the Kuhn Rikon Twist & Chop. I can reduce half an onion to a small dice in 20 seconds flat. Ten seconds to mince four garlic cloves. I’ve also used it successfully on apples, olives, and green peppers. Other vegetables also work, though it stumbles on very dense ingredients like nuts and carrots. The simple device is like a hand-powered version of a food processor, using a clever gear-driven design to create a fast, powerful spin of the blades. It’s a cinch to clean and really fun to use.
