The Ancient Aztec kitchen was a place where traditional dishes were prepared using ingredients native to Mesoamerica. To incorporate a coastal beach house theme with seashell accents, the kitchen can be designed with a vibrant color palette inspired by Aztec artwork. Seashell-shaped tiles can be used for the flooring, and seashell motifs can be incorporated into the kitchen cabinets and countertops. The walls can be adorned with Aztec symbols and artwork depicting coastal scenes. The kitchen can also feature a small chili pepper plant, reminiscent of the Aztec's love for spicy flavors.
