Why do some cooks put long aluminum nails through potatoes to be baked?
Originally Answered: Why do some cook put long aluminum nails through potatoes to be baked? Metal is a good conductor of heat. Heat will travel through the metal to the centre of the potato faster than it would through, say, potato flesh. … The metal prongs will assist this.
Should you wrap baking potatoes in foil?
Do not wrap potatoes in aluminum foil for baking. Foil holds in moisture and steams the potatoes, resulting in a “boiled” taste and texture. Turn the potatoes over halfway through the baking time to prevent browning of the undersides where they touch the baking tray or oven rack.
Do baked potatoes cook faster with or without foil?
Some say wrapping baked potatoes in aluminum foil helps them cook faster (aluminum conducts heat, then traps it), and it does keep them hot for longer once they come out of the oven, which is why we think restaurants use this method. Wrapping potatoes will also give you a softer, steamed skin, if that’s what you like.
What is the temperature for a baked potato?

Their skin also doesn’t hold moisture well, which makes for that ideal crispy exterior. Alternatively, sweet potatoes are a good choice.
Why does a jacket potato cook much more quickly if you put a metal skewer through it?
Answer: The skewer, which has mobile electrons to carry heat through it, provides an alternate path for heat to enter the potato and flow to its center. The skewer dramatically shortens the time it takes for the potato’s center to become hot.
Why does sticking a metal skewer through the middle of a potato make it cook faster?
Smaller potatoes have fewer particles, so heat takes less time to reach the centre. b) Why does sticking a metal skewer through the middle of a potato make it cook faster? Heat will be conducted through the skewer into the centre of the potato and it will cook from the inside out.
