People ask me for this old folk recipe all the time. Everybody claims that there is no commercial wallpaper paste that works as well and is free of pesticides!
- 1 cup flour (wheat, corn, or rice)
- 3 teaspoons alum
- 10 drops oil of cloves (natural preservative)
Combine the flour and alum in a double boiler. (If you don’t have a double boiler, set a smaller pan inside a bigger one that contains enough water that can be brought to a boil without overflowing). Add enough water to make a consistency of heavy cream; stir until blended. Heat, stirring constantly, until the mixture has thickened to a gravy texture. Let cool. Stir in the clove oil. Pour into a glass jar with a screw top. Apply with a glue brush.
Makes 1 cup. Shelf life: 2 weeks refrigerated.
