1/2 c. flour
2 c. cold water
Oil of peppermint, just a few drops

Mix together flour and cold water to make a creamy mixture. Boil over heat for 5 minutes, stirring constantly. Make sure it is a slow heat, otherwise it may burn. Cool. Then start to add oil of peppermint. This prevents spoiling. Thin down, if necessary, with a few drops of cool water if it is too thick. Store covered in refrigerator.
