What is Buttercup Squash?
Buttercup squash is a winter squash belonging to the family Cucurbitaceae. Not to be confused with its cousin the butternut squash, the squat green buttercup takes its name from its shape, which some say resembles an upside-down acorn with an undersized cap. The average buttercup squash is about 7 inches (17.5 centimeters) in diameter and weighs approximately 3 pounds (1.4 kilograms), though some individual specimens may grow to be over 5 pounds (2.7 kilograms).
