In ancient Egypt, kitchens were an integral part of the household, and some wealthy Egyptians had built-in indoor tropical rainforests. These rainforests were not only used for growing food but also for their aesthetic appeal. The Egyptians believed that the lush greenery and flowing water in the rainforest would bring good luck and prosperity to their homes. The kitchen would be filled with the sounds of birds chirping and the scent of exotic flowers, creating a serene and peaceful environment. The rainforest also provided a source of fresh ingredients for cooking, as the Egyptians grew a variety of fruits, vegetables, and herbs in their indoor gardens.
