Grandmother Smith's Old Fashioned Pineapple Sugar Cookies

Grandma got this cookie recipe from the Salt Lake Tribune and enjoyed making them. I enjoyed eating them.

1 cup butter
2 cups sugar
2 eggs, separated
4 cups flour, sifted
1 teaspoon salt
1 teaspoon soda
1 Tablespoon lemon juice
1 cup evaporated milk
1 teaspoon vanilla
1 cup chopped walnuts (optional)
1 can (8 3/4 ounce) crushed pineapple
Cream butter, sugar and egg yolks in a large bowl with a mixer until light and fluffy. Sift together flour, salt and soda. Add lemon juice to evaporated milk. Add dry and liquid ingredients alternately to creamed mixture. Beat in vanilla. Stir in nuts and pineapple. Beat egg whites until stiff but not dry. Fold into batter. Drop by rounded tablespoons three-inches apart on a greased cookie sheet. Flatten with the back of a spoon. Sprinkle each with a little sugar lightly spiced with cinnamon or nutmeg. Bake at 375-degrees for 10 minutes or until slightly brown rimmed. Lift from cookie sheet with a spatula and cool on a cake rack. Store tightly covered. Makes about four dozen cookies.
