Before You Begin


Though it seems simple enough, chopping is an important skill. Uniform pieces of onion (or other veggies, meat or chicken, for that matter) not only look impressive but cook evenly. Sharpen your knife before you start—it will cut more easily, making you less likely to hurt yourself.

Tip: To prevent tears, store onions in the fridge for 20 minutes before chopping.
