Unlike informal chopping, dicing is a precise cut that results in perfectly uniform pieces.
1.
Trim the item to be diced into a straight-sided cube or block. (Reserve trimmings for another use—they’re often great for soup.)
2.
Hold the block in place with your left (or non-slicing) hand. Curl your fingers under to hold the food securely while protecting your fingertips from cuts.
3.
Using correct slicing technique, cut the block into uniform slices that are the desired thickness of your finished dice. For instance, 1/4-inch dice begin with 1/4-inch slices.
4. Stack the slices, hold the stack in place, and cut through—again to the desired dimension—to produce uniform matchsticks.
5. Stack the matchsticks, hold them in place, and slice through once again to form dice.
