POTATO SOUP #3
Take 2 small teacupfuls of mashed potatoes to 1 1/2 pints of water. While that is heating mix 4 tablespoonfulls of flour in 1 quart of rich milk (the richer the better). When the potatoes have dissolved, stir in the mixture. Salt to taste. Pepper if liked. Have a quick fire and stir constantly to keep from scorching until it boils well.
