2 lb. blackberries
2 pt. malt vinegar
Place the washed blackberries in a bowl and break them up slightly with a wooden spoon. Pour on the malt vinegar. Cover with a cloth and stand for 3-4 days, stirring occasionally. Boil for 10 minutes, cool, strain and bottle the resulting liquid. This is very good for coughs. Quantities can easily be increased, allowing 1 lb. blackberries to 1 pt. fruit.
The same method can be used to make elderberry vinegar. Many people find this very good food colds – drink a tablespoon of blackberry or elderberry vinegar in hot water with a little honey.
