Butternut squash is named for its elongated nut-like shape. These squash are typically 8 to 12 inches long and 3 inches at the widest part. The orange flesh has a very sweet flavor.
Buttercup squash can be used in place of the butternut squash.
Both the wild and white rice can be made ahead. Cool the rice, then place it in resealable plastic food storage bags and refrigerate or freeze. Thaw frozen rice before using it.
