Place the potatoes in a large pot and cover them with cold water. Add the salt and bring to a boil. Reduce heat and simmer for 15-20 minutes, or until the potatoes are fork-tender. Drain the water and return the potatoes to the pot.
2 lbs Potatoes, 1 teaspoon Salt, Water
While the potatoes are cooking, heat a large skillet over medium heat. Add the bacon strips and fry until crispy.
8 slices Bacon
Transfer to paper towels so excess grease gets absorbed. Once cooled, crumble the bacon into medium large chunks. Reserve 2 tablespoons of the bacon grease.
Using reserved bacon grease, add the shredded cabbage and kale to the skillet.
1 lb Cabbage, 8 oz Kale
Cook for 5-7 minutes, stirring occasionally, until the vegetables are softened and slightly wilted. Set aside uncovered.
Add the butter, milk, and mace to the potatoes and mash until mostly smooth, leaving some small chunks for texture. Season with salt and pepper to taste.
½ cup Butter, 1½ cup Milk, ⅛ teaspoon Mace, 1 teaspoon Salt, ¼ teaspoon Pepper
Fold the cooked cabbage and kale into the mashed potatoes. Taste and adjust seasonings as needed.
Transfer the mash potatoes to a serving bowl, make a well in the center for the butter, and garnish with the chopped parsley and crumbled bacon.
¼ cup Butter, 2 sprigs Parsley
