Step‑by‑Step Instructions for Scottish Rumbledethumps
Step 1: Preheat Oven
Begin by preheating your oven to 350°F (175°C). While the oven heats up, take a moment to grease a 9×9 inch baking dish with 1 oz of butter to ensure a beautiful, non-stick surface for your Scottish Rumbledethumps casserole.
Step 2: Sauté Cabbage
In a skillet set over medium heat, melt 2 oz of butter until frothy. Add the thinly sliced cabbage and sauté for about 5 minutes, stirring occasionally, until the cabbage has softened and turned a vibrant green. This will create a flavorful base for your casserole.
Step 3: Combine Mixture
In a large mixing bowl, combine the boiled and mashed russet potatoes with the mashed turnips. Add the sautéed cabbage, the remaining 1 oz of butter, kosher salt, and freshly ground black pepper. Mix everything thoroughly until well combined, ensuring a beautiful blend of flavors for your Scottish Rumbledethumps.
Step 4: Transfer to Dish
Spread the hearty mixture evenly into your prepared baking dish, using a spatula to smooth the top. Generously sprinkle the grated sharp cheddar cheese atop the mixture, creating a deliciously gooey topping that will melt and brown beautifully during baking.
Step 5: Bake
Cover the baking dish with aluminum foil to lock in moisture and bake in the preheated oven for 30 minutes. After this initial baking, remove the foil and bake for an additional 5 minutes, or until the cheese is lightly browned and bubbling—that perfect visual cue of a well-cooked Scottish Rumbledethumps.
Step 6: Serve
Once out of the oven, let the casserole rest for about 5 minutes to set before serving. This waiting time will enhance the texture, making it easier to cut and serve, while the inviting aroma fills your kitchen, ready to offer warmth and comfort to everyone at the table.
