In October, there are so many pumpkins for sale for carving and decoration. (In fact, every year Americans buy about 1.1 billion pounds of pumpkins, according to the national Agricultural statistics service.) Seeing all this American plenty got me energized to cook them. Whole pumpkins come in so many different shapes, sizes, and colors, so rather than developing a one-size-fits-all recipe, I came up with two different cooking methods, based on size. We are not going to mislead you into thinking there is a secret equation that x pounds of pumpkin equals x cups of puree. larger pumpkins can have less puree if they are hollow. Some small pumpkin varieties have more flesh.
