The night before Thanksgiving, I stayed at my brother's house in prep for the big day to come. After a long day of traveling we unwound with cocktails he mixed up in his home bar, but as I sleepily tottered off to bed, my sister-in-law disappeared to "make a few things for tomorrow." In the morning, it was as if the Christmas elves showed up early. Besides the various delicious deviled eggs and stuffed celery appetizers, she had made marshmallows! Boy, were they amazing.
