Because sugar from the West Indies was produced with slave labor, the maple pie is recognized as a symbol of New England's values of self-sufficiency and economic independence.
In anti-slavery New England William Fox and others advocated for the boycott of sugar from the West Indies to pressure slaveholders.
The tradition of making maple pie, although not as common as it used to be, continues to symbolize New England values of a simple lifestyle and economic independence.
Cornstarch is added to the sweetened milk to make a thin paste which is poured over beaten eggs, then cooked all together for one minute.
The maple custard is cooled and poured into the pie shell, served topped with whipped cream.
