一单字动词，表示给食物过冷水，是哪个字？ / a single-character word meaning to submerge food in cold water 北京话里有个单字动词，表示给食物（比如刚煮熟的面条、蔬菜等）过冷水。华北其他地区可能也说。请问这是哪个字？以前经常听人说，现在记不清了。

There is a single-character verb in Beijingese Mandarin, meaning to submerge food (like boiled noodles, vegetables, etc.) in cold water. It is possibly used in other parts of Northern China as well. May I know which word is this? I used to hear it a lot but forgot what it exactly was.
拔（pronunciation only. Not sure how to write.）。
e.g. 面条放冷水里拔一下

焯是过热水。
