Cooking Instructions:

Wash the potatoes and cook in boiling salted water for 20 minutes. 2 Strain and cut in half lengthways. Using a spoon, scoop out the potato into a bowl, being careful not to break the skins. 3 Mash the potatoes in the bowl and add the ham and butter. Mix together well. 4 Put this mixture back into the potato skins, and place in an ovenproof dish. Sprinkle the grated cheese on top, and grill for 10 minutes. The potato was grown by the Incas, and was discovered in Peru by Pizarro. It was brought to Europe in 1534
