From 1922:

Boil together 3 cupfuls of granulated sugar, 1 ½ cupfuls of water and 1 quarter of a teaspoonful of tartaric acid until on trying in cold water it will almost crack, but if held a moment can be rolled into a hard ball. Do not stir, but pour into a buttered dish to cool. As soon as it can be handled add 1 teaspoonful of extract of peppermint, and pull until it is white, then cut into sticks.
