We scrubbed the potatoes clean with the little vegetable brush, and then made a cut right around each of them through the outside skin but not through the potato. Then we put them in a moderate oven and baked them till they were very done. It took nearly an hour because they were big fellows. Mother showed us how to test them to see whether they were done. Not with a fork this time, but with a clean dish towel. She had us take them out of the oven and hold them in the cloth, pressing them to see whether or not they were soft.
Note: Moderate oven here is 350 - 375º F.
When we found that they felt soft and mealy inside, we took them out and cut each one in two right around its waist, exactly where it had been marked with the knife before.
Then we each took all of the mealy potato part out of the skin of our potatoes with a big spoon. We put it in a bowl. (We were very careful not to break the skins while we were doint it, too. And we saved the skins.) When the soft potato was all in the bowl, we mashed it up with a potato masher till there waasn't a single lump in it. (Robin helped Ruth Ann but I did mine every bit alone.)
Then when all the lumps were out but the potato was still hot, we added the butter, salt, paprika and hot milk. Then we beat it some more just as hard and fast as we could, to make it light and fluffy.
When the potato mixture was fluffly and white, we piled it back in the skins again. Mother said not to mash it down but to pile it up roughly and lightly. When the potato cases were all filled we sprinkled the grated cheese over the tops. (Our cheese happened to be hard and dry so we could grate it easily. Mother says when the cheese is fresh and soft, to cut it up in very fine little pieces instead of grating it.)
Then we put all the potatoes in pie pans and set them in a hot oven for fifteen minutes. When we took them out the tops were all a beautiful light brown color. We had them for lunch without any meat because Mother told us the cheese in the potatoes would take the place of meat. My, they tasted good!
Note: A hot oven as directed here is 400-425º F.
