Slicing ginger diagonally maximizes its surface area, releasing more flavor and aroma into your stir-fries or tea. It also creates visually appealing slices.
When you slice ginger diagonally, you're essentially cutting across more of the ginger's fibers. This increased surface area allows for a greater release of the flavorful oils and compounds that give ginger its characteristic zing. Think of it like this: a flat, straight cut exposes less of the ginger's interior compared to a diagonal cut. The diagonal cut also creates thinner, more delicate slices that cook more evenly and infuse their flavor more readily into the dish or beverage. Furthermore, the elongated shape of the diagonal slices adds a touch of elegance to the presentation, especially in stir-fries where visual appeal is important. The diagonal cut also helps to break down the tough fibers of the ginger, making it easier to chew and digest.
Use a vegetable peeler to remove the ginger's skin before slicing. This is much easier and less wasteful than using a knife.
