How to Make It
Place the potatoes in a large saucepan and add enough cold water to cover by 1 inch. Add 1 teaspoon salt and bring to a boil. Reduce heat and simmer until very tender, 20 to 25 minutes. Drain and return the potatoes to the pot. Add the butter, milk, and ¼ teaspoon pepper and mash to the desired consistency.
Meanwhile, cook the meatballs according to the recipe directions.
In a large skillet, bring the jelly and allspice to a simmer. Add the meatballs, toss to coat, and cook until the mixture is slightly thickened and coats the meatballs, 3 to 5 minutes. Serve with the mashed potatoes and sprinkle with the dill.
