Mom's Stuffed Baked Potatoes

This was written on a very spotted recipe card, so I would imagine it was used allot.

4 large baking potatoes

1/4 cup melted butter or oleo

Hot milk

2 slightly beaten egg yolks

Salt and pepper to taste

Scrub potatoes: rub skins with fat. Bake in hot oven 425- 45-60 min. or till done. Cut potato in half lengthwise and scoop out inside. Mash, add butter and enough hot milk to beat light. Add yolks, beat till fluffy. Season to taste. Pile lightly into shells. Rebake.
