Due to last minute change of plans on Monday I have 3 cold oven baked potatoes in the fridge. I want to do twice baked potatoes with them tonight but from previous experience, I know cold potato is very tricky to mix/mash so I feel like I need to heat it up first. How should I do it? In the microwave? Still in the skins or should I take it out first?
Any advice gratefully received!
