This truly was my favorite dish when I was growing up. My mom preferred to cook our food without sugar so she did not glaze the squash. We loved it with just butter and salt and pepper. I don't think there is any better way to cook it. Simple. Plain, Absolutely mouth watering! I always added more butter at the table, too. It was lovely seeing that puddle of butter in the bottom of the squash, then mashing it all together inside the skin. Good eats!!
Place face up in baking dish. (To cup the butter inside. It is OK if it leans a little... just so long as it holds the butter without dripping. Trim a tiny flat place off the bottom if necessary -- or cradle on a clean metal jar lid.)
