You can buy special baking potatoes but ordinary potatoes will bake just as well.
Ingredients
Potatoes
Salt
Wash the potatoes well making sure you get all the wee bits of earth out of the eyes. Take a fork and jab the potatoes all over, then rub salt into them. Put on a baking tray and bake on the middle shelf of a medium oven for about ninety minutes. Depending on the size of the potatoes, they may take more or less time to bake but when they are ready it should be easy to stick a knife in them right to the centre.
