Old Sugar Cookie Recipe

Hi, I copied down my Great-Aunt's Sugar Cookie recipe incorrectly, and I can not find an original copy of the recipe. I wrote down baking soda twice. Has anybody ever made this recipe? Could you tell me the correct ingredients after sour milk and before the flour?

2 cups sugar 1 cup lard 2 eggs 1 cup of sour milk 1 teaspoon baking soda 1 teaspoon salt 1 teaspoon. baking soda approx. six or more cups of flour

any help would be greatly appreciated thank you
