You can leave basil leaves whole and add them to salads and hot dishes toward the end of cooking, tear them into pieces for more capricious basil flavor, or thinly slice them. To avoid bruising the basil, slide a sharp knife down and across the basil with a deliberate, smooth stroke. A clean cut will darken the leaves less than a pounding cut.
To slice basil, first stack the leaves together.
You can either roll them up like a cigar and slice through them to make a chiffonade, or just slice away at them as they are.
