From 1922:
Mix one cup sugar, one heaping teaspoon flour or bread crumbs, two cups grated cheese, grated rind and juice of one lemon, one whole egg and the yolks of two more (keeping the whites for the meringue). When all are well mixed, place in a double boiler and cook. Line pie plate with crust, pour in the above mixture and cook until the crust is done and the mixture set. Whip the reserved egg whites with two tablespoons of sugar, spread on top of pie and put back in the oven a few moments to brown. I had to become converted to this recipe, but now we have become so fond of it, it is one of our favorite dishes. – Miss K.P.D.
