12 ounces ice, solid
2 1/2 cups white sugar
3/4 teaspoon salt
3 eggs
1/2 cup milk
1 cup all-purpose flour
2 cups nearly-boiling water
4 teaspoons vanilla extract

Line a 20-inch square tin with foil because foil can be sticky. In a large saucepan, combine sugar, 1/2 cup of milk and 3/4 of the flour; stir until smooth. In a large bowl, cream the rest of the milk and the flour mixture. Beat in the eggs one at a time. Stir in the vanilla and nuts. Gradually stir in the flour mixture, 1/2 cup at a time, beating well after each addition. When the dough has pulled together, turn out onto a lightly floured surface and knead until smooth and elastic, about 8 minutes. turn out onto a lightly floured surface and divide dough in half. Roll out dough and press into prepared pan. Chill 10 minutes before serving.
