Julienning vegetables
To julienne a vegetable, first trim the vegetable, like a radish or carrot, so it’s flat on all sides. Slice it lengthwise into 1⁄8-inch thick pieces. Stack the pieces, and slice them into strips of the same width. The figure shows an illustration of this technique. Illustration by Elizabeth Kurtzman
Cubing (or dicing) vegetables
Dicing is the same as cubing, except that your pieces are smaller: 1⁄8 to 1/4 inch, usually.
