PLAN No. 209. VINEGAR MADE PROM STRAWBERRIES
Thoroughly mash a quantity of ripe strawberries into a paste, and let stand for 24 hours. Then press out the juice and let it stand for a few days, to ferment and to allow the slimy contents to separate. Then filter the juice and put into clean, well-closed bottles, and put in a cool place, where it will keep a long time. Added to good cider vinegar, when ready to use, it makes an excellent flavoring.
It was cheap and easy to make, and profitable to sell.
