Korean Pork and Asparagus Stir-fry

The pork is sliced thin and marinated in soy sauce, minced garlic, and a pinch of sugar for ten to fifteen minutes; the sugar draws moisture to the surface and promotes caramelization, creating a glossy, slightly browned crust when the meat hits the hot pan. Cooking the meat first over high heat renders out its fat, which becomes the stir-frying medium for the vegetables that follow - a technique that layers the pork's savory quality into the whole dish rather than keeping it confined to the meat alone. Asparagus goes in for barely a minute: enough time to eliminate the raw, starchy taste while preserving the clean snap of the stalk. The fibrous base of each spear benefits from a quick pass with a vegetable peeler before cooking, which allows the thicker portions to cook at the same rate as the tips. Bell pepper adds natural sweetness and a visual contrast to the green and brown of the other components. The sauce - soy, a touch of oyster sauce, and sesame oil - is deliberately restrained; a single spoonful of oyster sauce adds enough viscosity to help the seasoning cling evenly to every piece without making the dish heavy.
