If you don't stack leaves evenly before chiffonading, you'll end up with unevenly sized ribbons, some too large and some too small. This affects the presentation and texture of your dish.
Chiffonade is a cutting technique used to create thin ribbons of leafy greens or herbs. The process involves stacking the leaves, rolling them tightly, and then slicing the roll perpendicular to its length. The key to a successful chiffonade is uniform stacking. When the leaves are unevenly stacked, the resulting roll will have varying thicknesses. This means that when you slice the roll, some slices will be much wider than others, resulting in inconsistent ribbons. Imagine trying to slice a log that's thicker on one end than the other – the slices will be different sizes. This inconsistency can negatively impact the visual appeal of your dish and the overall eating experience, as some bites will have a much larger or smaller amount of the herb or green than intended.
To ensure even stacking, gently pat the leaves down as you stack them to remove air pockets and create a compact, uniform pile. This will help you achieve consistent, beautiful chiffonade ribbons every time.
