Butternut Squash Soup

When cooler weather overtakes the waning summer heat, call back the warmth with a classic autumn soup that envelopes the taste buds with the sweet, nuttiness of winter squash, a blend of harvest flavors—carrots, celery, and apples—and a tickle of curry powder and ginger. Don’t skip the garnish of cashews (for a hearty crunch) and raisins (for chewy sweetness). The result: a complex and delicious fall soup.
