I was officially introduced to the American public at the 1876 Philadelphia Centennial Exhibition. I am one of the few fruits that ripen best off the plant. If left on the plant, I will split open and my interior will have a “cottony” texture and flavor. I am produced the most in India, growing 16.5 million tonnes in 2002, followed by Brazil which produced 6.5 million tonnes of in 2002. What am I?
