 Food was often stored in a buttery separate from the main house, which was designed to keep food cool.This was achieved by keeping the actual storage room raised above the ground, typically five or six steps worth of height, and using a pointed roof, enabling convective heat transfer to keep warm air from the food.Kitchens were also distinctive, occasionally placed in out-buildings or in basements and noted for the use of wide, raised chimneys possibly inspired by the open hearth.
