My P.S. (Prefers Sweet potatoes/ hubby) hound this years’s new Thanksgiving recipe. He was reading the Parade insert in our local newspaper and asked what I thought. I thought ‘blog post’, of course! Not a huge fan of sweet potatoes unless there’s bourbon and candied pecans, I was pleased to see there was a good amount of Gruyere in the dish. With my P.S. willing to mandolin the potatoes for me, we had a deal. Gratin would happen.
The dish isn’t a cheap one: after buying Yukon gold potatoes, sweet potatoes and a $14 of Gruyere, I hoped it was worth it. With just the two of us at Pandemic Thanksgiving, the recipe said it served 10. This pleased my P.S. since it meant leftovers. He might be eating them alone, I thought.
Early Thanksgiving morning my P.S. peeled the potatoes then sliced them with the evil mandolin. He loves to use that thing; I do not. i cut myself just putting it away one time. That was enough.
While he prepared the potatoes, I ground up some rosemary. We aren’t huge fans so I used dried rosemary and ground it in my spice grinder. It would be easier to sprinkle on the layers in a smaller amount.
I also shredded the Gruyere. I waxed nostalgic, remembering all of the years I shredded cheese, before shredded cheese in packets dropped in price and became the new normal. Now we have 8-10 different kinds of shredded cheese in the cheese drawer at any given time. Life changes!
I used a glass baking dish for the gratin. I buttered it well and again mused: I don’t do that often anymore either. The invention of cooking spray is one of my favorite advances. Pssssst and done! But this gratin deserved the real thing. Butter.
The cream and garlic were stirred together in a bowl and poured over the potato layers. A last layer of the reserved cheese and the gratin was ready.
A layer of heavy foil was placed on top and the dish went into the 450°F oven. I set the timer for one hour.
My P.S. immediately said we must make this again. He thought it needed a bit more salt next time. I agreed. And I disagreed with the directions, it doesn’t serve 10. I’d say more like 6 because you’ll want to eat a lot of this gratin!
