I keep a jar of honey in one of my kitchen cupboards, but never really thought about how to best store it until I read a short article in a hundred-year-old magazine. (When I read the article, I also realized that I never even considered storing honey in some of places where people apparently put it in 1919.)
How to Keep Honey
In using honey as a substitute for sugar, the housewife may encounter some difficulty through lack of knowledge in storing this product according to the American Food Journal. Housewives usually put their honey in the cellar for safekeeping, probably the worst possible place, as honey absorbs moisture from the atmosphere, and will become thin and in time sour. Comb honey kept in a damp place will be hurt in appearance, as well as in quality. A practicable rule is to keep honey in any place where salt remains dry. If honey has granulated or candied, put the can containing it in a large vessel holding water, not hotter than the hand can be borne in. If the water is too hot, there is danger of spoiling the color and ruining the flavor of the honey. The can of honey should be supported by a block of wood in the vessel of water, so that the heat from the stove will not be too intense.
