""This pasta," Mario Batali says, "always propels me into fall." You can substitute pumpkin or hubbard squash?whichever looks more beautiful at your market?for the butternut. "Cook the squash until it's soft but not falling apart?you don't want al dente squash, but you don't want mush either," Batali says...."
