My brother-in-law is an incredible cook. If he weren’t an excellent physician, he’d own a restaurant and be a highly-regarded chef, I’m sure.
So when he has tips for how to do something in the kitchen, I always listen. Here, he’s demonstrating how he dices an onion. Which is now how I dice an onion.
BTW, that’s the Cardinals on in the background, losing to the Reds. Ohwell. The food was amazing.
That is similar to the way they teach you to do it at the Viking Cooking Classes. They also have you do a horizontal cut as well. Fabulous santoku knife, but the Viking people would faint if you cut on a paper plate! Only sturdy cutting boards allowed.
