What temperature would a "quiet oven" be in old fashioned temperature vocabulary?
Google Books has a number of results calling for a "quiet oven" in older recipes, but it seems to have been such a ubiquitous concept that they didn't feel the need to explain what it meant. The only source I could find that gave any indication at all was this book by Robert Carlton Brown, published in 1955, which indicates that it was an English term for a "moderate" oven. He doesn't say what that specifically means, or when it fell out of favor as a term (I would assume with the advent of electric ovens), but I would posit that it's somewhere around 350-75 degrees, based on modern usage.
