Have you ever had a baked potato at a restaurant which has lost all that wonderful fluffy quality and is just leaden and soggy?
That’s because it was wrapped in foil. I guess they think that it keeps them warmer longer or something but all it does is ruin the texture completely.
If I know that a restaurant routinely wraps them in foil, I will NEVER order the baked potatoes there. If I’m in an unfamiliar restaurant, I’ll always ask the server if the baked potatoes are foil wrapped. If so, I always order something else.
Wrapping them in foil is a horrible horrible idea and I have no idea which “genius” thought it up in the first place.
If you want your potatoes to heat up faster give them a light coating of oil. This improves heat conductivity a bit and if you’re the type who eats the skin, it leaves it more crispy.
