What were the ingredients in Dominican Puerto Rican or Mexican food during the Columbian exchange?

During the Columbian Exchange, Dominican, Puerto Rican, and Mexican cuisines were transformed by the introduction of new ingredients from the Americas and Europe. Key native ingredients included maize (corn), beans, and squash, which formed the basis of many dishes. Additionally, the exchange brought European staples such as wheat, rice, and various meats, along with spices and herbs from both sides. This fusion created a rich culinary tradition that combined indigenous and European flavors and techniques.
