Pumpkin: Jack-O-Lanterns, muffins, lattes and of course pie.
Some world records on pumpkin carving from Wikipedia:
From 2003 to 2006, the Pumpkin Fest at Keene, New Hampshire held the world record for most jack-o’-lanterns carved and lit in one place—28,952. Boston, Massachusetts stole the crown in 2006 with 30,128 jack-o’-lanterns simultaneously lit on Boston Common. Highwood, Illinois captured the record in 2011 with 30,919 pumpkins aglow.
The world’s largest jack-o’-lantern was carved from the world’s then-largest pumpkin in 2005 in Northern Cambria, Pennsylvania. The pumpkin weighed 1,469 pounds (666.33 kg).
