A Summer Kitchen
Many large homes and estates in New England have a smaller home nearby on the same property. The smaller home isn’t connected to the main house. These little houses were known as summer kitchens are they would typically be fully equipped with large fireplaces and stone ovens.
Slaves would work in these kitchens to make food for the family they were serving. The kitchens were outside the house so that the stove and fireplace wouldn’t heat up the house while the slaves were cooking.
