Elder-flower Vinegar. No. 3.
Pick the flowers before they are too much blown from the stalks, and dry them in the sun, but not when it is very hot. Put a handful of them to a quart of the best white wine vinegar, and let it stand a fortnight. Strain and draw it off, and put it into a cask, keeping out about a quart. Make it very hot, and put it into your cask to produce fermentation. Stop it very close, and draw it off when wanted.
