Hydrogen, oxygen and carbon make up about 99% of the average human. I'm going to cheat a little and leave out the other 1%, which is made up of trace elements (that is, stuff there's only a trace of in the body). Then, let's assume an average adult weighs 70 kilograms.
DONâT! Youâll end up with the potato getting steamed in the foil instead of just baked. You may as well just cook it in the microwave. Place the potato directly on the oven rack. Bake for 40 to 60 minutes, depending upon the size of the potato.Potatoes are as hard as a brick when they are raw. By the time itâs cooked youâll be able to squeeze it.he oven needs to be really hot, 400 degrees hot, when you stick the potatoes in it. So before we go any further, go turn the oven on to 400 degrees to preheat. (This could take up to 15 minutes, maybe even longer depending on your oven.). All potatoes need to get washed first. A vegetable scrub brush works beautifully.
Best Answer: Cooking Temperatures for Perfect Baked Potatoes Everytime: Conventional or Regular Oven: Medium-size potatoes (about 5 ounces or 150 grams each) 45 minutes at 400 degrees F. 60 minutes at 350 degrees F. 90 minutes at 325 degrees F. Place the potato directly on the oven rack in a preheated oven. Potatoes are done if tender when pierced with a fork and the internal temperature reaches 210 degrees F. --------------------------------------... Bake on racks of oven until tender. The higher the oven temperature, the shorter the cooking time will be and the crustier the skin.
