I'm making little roasty potatoes for with dinner today. Usually I prep my potatoes before hand by chopping and putting in a bowl of water to stop them discolouring. I then dry them off when I'm ready, pop on a baking tray and cover in olive oil, salt, pepper, garlic and rosemary. They never go as crispy as i would like though. I was thinking today that I'd prep them and pop them in a bowl then cover in the olive oil, salt, pepper and garlic then just use them when I'm ready (couple of hours time). Will they discolour? Will it work? Someone please help!
