Bean curd sticks are a soybean product made by grinding soybeans into paste, boiling it, then coagulating and drying it. They are produced by first removing the skin from the pot, straightening the strands, rolling them into rods, and drying them. They are cooked.
Can bean curd sticks be eaten raw?
As a cooked dried product, bean curd sticks can be soaked in water, seasoned, and served as a cold salad. However, for safety, it's recommended to blanch them in boiling water for 3-5 minutes first to kill surface bacteria.
Should bean curd sticks be soaked in hot or cold water?
Cold water is best for rehydrating bean curd sticks, typically requiring 5-7 hours. If preparing a cold dish afterward, briefly blanch in boiling water for 3-5 minutes to sterilize. For stir-frying, simply drain and cook directly.
While hot water soaking reduces time, it can cause the surface to disintegrate, resulting in soft crumbs during stir-frying and an unappealing appearance. Additionally, uneven rehydration may occur—the surface becomes overly soft while the interior remains unsoftened, significantly compromising texture.
