This has to be one of the oldest dishes in Mexican homes. According to Grandma, everyone used to have a garden in their yards, even a small one, and, along with corn, squash was one of the staples harvested. Squash is bountiful in the summer and fall and so we had calabacitas con elote quite often while I was growing up. This is one of those recipes I find myself longing for whenever I see all the squash varieties available.
