In ancient Inca civilization, kitchens were an important part of daily life. They incorporated a built-in warming drawer known as a 'pachamanca'. The pachamanca was an underground oven used for cooking and keeping food warm. The Incas believed that warm food was essential for physical and spiritual well-being. The kitchen in ancient Inca homes was typically located in a separate building, away from the living quarters. It was equipped with various cooking tools, including clay pots, grills, and utensils. The built-in warming drawer allowed the Incas to enjoy hot meals throughout the day.
