To avoid injury while dicing onions, use a sharp knife, curl your fingertips back to protect them, and maintain a stable cutting board.
Dicing onions can be a tearful and potentially dangerous task if proper safety measures aren't followed. Here's a step-by-step breakdown to minimize the risk of cuts:
Use a Sharp Knife: A dull knife requires more force, increasing the likelihood of slipping. A sharp knife cuts cleanly and with less effort.
Prepare Your Onion: Cut the onion in half through the root end. Peel the outer layers, leaving the root end intact. The root end helps hold the onion together during dicing.
Make Horizontal Cuts: Place the flat side of the onion half down on the cutting board. Make horizontal cuts into the onion, stopping short of the root end. The number of cuts depends on the desired size of the dice.
Make Vertical Cuts: Now, make vertical cuts down through the onion, again stopping short of the root end. The spacing of these cuts determines the size of the dice.
Dice: Finally, slice across the onion, perpendicular to the previous cuts, releasing the diced pieces. The root end can now be discarded or used for stock.
The Claw Grip: This is crucial. Curl your fingertips inward, so your knuckles are prominent. The knife blade should rest against your knuckles as you guide the onion. This prevents the blade from cutting your fingertips.
Stable Cutting Board: Ensure your cutting board is stable and won't slip. Place a damp cloth or a non-slip mat underneath it.
Never try to catch a falling knife. Step back and let it fall. It's better to replace a knife than to risk a serious injury.
