Corn
Step-by-step explanation:
Spices came from the India area mostly.
Porcelain and silk mostly came from China and Japan.
Corn originates in America. We found traces of corn dating back more than 5,000 years in areas where Mexico is. We even found traces of popcorn dating back more than 3,000 years. Corn was not known elsewhere before it was exported from the American continent, and that region is not pat of the Far East.
