Alison Roman's Crushed Sour Cream Potatoes are good enough to make you want to tweak your Thanksgiving menu.
4 pounds small, creamy potatoes, no larger than a gold ball, such as gold creamer
Kosher salt and freshly ground black pepper
2 cups heavy cream
6 large garlic cloves, crushed
4 tablespoons unsalted butter
1 cup sour cream, plus more for serving
½ cup finely chopped chives
1/3 cup coarsely chopped dill
Cook potatoes in a large pot of boiling, salted water until tender, 10 to 15 minutes. Drain. (This step can be done ahead of time; keep potatoes covered and warm on the stovetop.)
Meanwhile, in a medium pot over medium heat, gently simmer the cream and the garlic until garlic is completely tender and cream is reduced by about a third (it will look slightly thicker, about the consistency of melted ice cream), 8 to 10 minutes. Season with salt and lots of pepper. Add butter and swirl to melt. (This can also be done ahead; rewarm before proceeding.)
Using your hands or something like a small dish or bowl, crush the potatoes and place in a large bowl. Pour cream mixture over the potatoes, and season with salt and more pepper. Toss to coat, encouraging the potatoes to break down slightly but remain textured and chunky.
Stir in sour cream, half the chives and half the dill. Transfer to a large serving bowl and top with remaining chives and dill, and more black pepper and sour cream, if you like.
