Mashed potatoes
Hi, quick question:
I am cooking for 8 in a couple weeks. I want to cut down on prep time, so I am wondering can I peel potatoes ahead of time for mashed potatoes ? How far in advance? Will they discolor ? Could I peel and chop the night before and then boil next day?

As for peeling, quartering and leaving in water overnight, my mom and I have both always done that, and it works well. I wanted to add, though, that one time I was going to boil thinly sliced potatoes (for use in a Spanish tortilla), and somehow the potatoes, when left overnight in the water, got a little stinky. The obvious difference between the thin slices and the quartered potatoes is surface area, but I don't know exactly why that happened.
As for making ahead, I've done it two different ways. I've made the potatoes, put them in a baking pan and reheated them in the oven, and I've also reheated them in a pot. Both ways, I've found it necessary to add extra liquid -- warm milk and butter is best -- to bring the potatoes back to the consistency I like. I've sometimes been surprised at the extra amount I've added, particularly when I re-heat in a pot (what I usually do), but it really brings the potatoes back to a luxurious texture with no harm done from having been made ahead.
