Using a towel or oven mitt, take the pot of potatoes from the stove and empty into a colander placed in the sink. You’ll see lots of steam rise up – let it go, the steam is taking some of the water out of the potatoes. Some professional cooks, so intent on a dry spud, place the cooked potatoes on a cookie sheet and stick in a preheated 300-degree oven to get rid of the water.
