After the Bird – Sweet Potato-Topped Turkey Casserole

Early in the summer, Gilbert’s mother, Virgen, gave me a sweet potato that had sprouted, knowing I love to grow things, especially food.  After a bit of research, I learned that you can cut off the sprouts, put them in water to root them, then put them in the garden and grow your own sweet potatoes. Awesome!

Just about a month ago, we had our first hard frost. That’s the time to harvest sweet potatoes. The potatoes continue to grow and get bigger into the fall until the first frost. What started out as a simple 1/2 hour job harvesting my 3 sweet potato vines turned into an all day chore. Did I have a bumper crop? NO! I have rocky New England soil! The first rock of considerable size I hit while harvesting turned out to be about 50 pounds.  Eric helped me move it out of the garden.  The next one was just 40 pounds and Eric easily lifted that out for me. Then came a massive rock the size of a Galapagos sea turtle (200-300 pounds for those of you who don’t know the mass of a Galapagos sea turtle!) We had to use a ramp and levers to pry it out of the ground and roll it out of the garden. But I got my potatoes all dug out and while they were pretty small, I’m excited to grow more next year!

The biggest of the rocks that was unearthed during the sweet potato harvest. The Dr. Pepper can is there to give perspective on the massive size of the rock!

We’re making this recipe to use up some of our Thanksgiving turkey and the mashed sweet potatoes!
