To Clean: Wash squash thoroughly in cold water. Cut in half and remove seeds and fiber from center of squash. Winter squash may be baked in halves or pieces without peeling or may be peeled and cut into chunks for mashing.
To Steam: Peel squash and cut into 1 1/2-inch chunks. Arrange on steaming rack. Place over boiling water; cover and steam 15 minutes or until squash is tender.
Remove from heat, and sprinkle with brown sugar. Steam an additional 5 minutes. Transfer squash to a serving dish; dot with butter, and toss lightly to coat squash well.
Other Cooking Methods: Bake.
