Delicata squash gets cooked two different ways here, to really take advantage of all it has to offer: half of it gets caramelized until just tender, while the remainder continue to cook down until soft and jammy. The jammy bit becomes the thickening agent for this quick ragù, while the tender pieces stay whole, lookin’ all pretty as they tumble around with spicy sausage and rigatoni. But, the real secret to this sauce is mellow white miso paste which imparts a decidedly savory depth of flavor---a perfect foil to sweet Delicata squash and an all around bang up addition to your pantry if it’s not already in there.
