In this video from FoodNetworkTV Chefs Anne and Beau teach the Worst Cooks in America how to chiffonade basil. This is a knife skill. This give the basil a "ribbon" look to it. To do this, layer 3 or 4 leaves, then roll the basil, then you make tiny slices in that basil and be careful to watch your fingers! Then you unroll the basil and you have little ribbon cuts of basil that can be used to make a lovely garnish for any plate!
