Hundred-year-old cookbooks often contain household tips. Sometimes they leave me scratching my head or wondering if they really work. For example, I had my doubts about the following tip:
When boiling old potatoes, put a tablespoon of milk in the water in which they are cooked and they will be much whiter.
General Welfare Guild Cook Book (Beaver Valley General Hospital, New Brighton, PA, 1923)
When I saw the tip, I could think of no reason why boiled potatoes would be whiter if cooked in water that had a little milk added. And, I wondered why anyone would care. My boiled potatoes generally look fine (even if they are cream colored).
When I tried this tip, I think (much to my surprise) that it actually worked. The potatoes seemed whiter than usual.
This tip also made me wonder about the use of the term “old potatoes.” Is there such a thing as old potatoes in today’s world? When I was young, I can remember potatoes starting to sprout, and getting soft and mealy in the spring – but I seldom see those types of potatoes during any season any more.
