An Indian name, in universal use in New England, New York, and other Northern States, for boiled Indian meal.
The common food of the Indians is pap, or mush, which in the New Netherlands is named supaen. This is so common among them, that they seldom pass a day without it, unless they are on a journey or hunting. We seldom visit an Indian lodge at any time of day, without seeing their supaen preparing, or seeing them eating the same. It is the common food of all; and so fond of it are they, that when they visit our people, or each other, they consider themselves neglected unless they are treated with supaen.--Van der Donck's New Netherlands, (1656,) N. Y. Hist. Soc. Collections
The flour [of maize] makes a substantial sort of porridge, called by the Americans supporne; this is made with water, and eaten with milk.--Backwoods of Canada, p. 189.
