Culinary Notes
The Two-Part Rule: You must treat the white and green sections as different vegetables. Sauté the white and light-green bases early in the cooking process in oil or butter to build your flavour foundation. Reserve the delicate, dark green tops to slice thinly and scatter over the finished dish completely off the heat, preserving their crunch and vibrant colour.
The Bias Cut: For a professional, elegant garnish, slice the green tops on a sharp angle (on the bias). This exposes more surface area, releasing more of the volatile aromas and causing the pieces to curl slightly on top of a soup or stir-fry.
The Charred Sweetness: Spring onions are spectacular when subjected to intense, direct heat. Tossing them whole in a little oil and blistering them on a grill or in a smoking-hot cast-iron pan wilts the greens and rapidly caramelises the natural sugars in the bulb, creating a sweet, smoky side dish.
The Regrowth Trick: Never bin the hairy root ends. If you leave about an inch of the white base attached to the roots and stand them in a shallow glass of water on a sunny windowsill, they will rapidly regenerate new green shoots within days.
