Instructions
Bring a pan with about 4 inches (10 cm) of water to a boil.
Cook the kale and potatoes in the pan with boiling water until done in about 20 minutes.
14 oz. kale, 2½ lbs potatoes
Preheat the oven to 430 °F or 400 °F
After cooking the potatoes, mash them.
Add the kecap, diced cheese, salt, pepper, and dried tomatoes and stir through.
10 sun-dried tomatoes, 3 oz. Gouda cheese, 3 tablespoons Kecap Manis, ¼ teaspoon salt, ⅛ teaspoon ground black pepper
Spoon the mixture into the baking dish (13 × 9 inch / 30 × 25 cm) and top it with the grated cheese.
2 oz. grated cheese
Put the casserole in the oven for 15 minutes until the cheese is melted.
NOTES
1. Potatoes: Use floury potatoes to make this recipe. Russet potatoes, Doré, King Edward, Yukon Gold potatoes, and Maris Piper, are excellent choices. They're the best for preparing a mash.2. Kecap Manis: Kecap Medja, or sweet soy sauce, a surprising ingredient that adds a delicious flavor to the mash. It's sweet and dark brown and adds a soy sauce flavor; if you don't have it, replace it with one tablespoon of all-purpose soy sauce and two teaspoons of dark brown sugar.3. Cheese: I prefer Gouda cheese, but you can substitute it with cheddar or Emmentaler. Use freshly grated cheese if you can. It tastes better because it doesn't contain anti-caking agents, which can give a slightly powdery feel.4. Variations
Add two tablespoons of butter to the mash for more creaminess.
Vegan recipe? - Use vegan cheese instead of Gouda.
5. Storage
Prepare in Advance: You can make the dish in advance the day before. Store it covered with foil in the refrigerator. Bake it for 30 minutes in a preheated oven at 430 °F (220 °C).
If you've got some leftovers? Top it with baking paper and then with foil, and store it for up to two days in the refrigerator. Next, bake for 30 minutes in a preheated oven at 430 °F (220 °C) while covered with aluminum foil.
You can store the dish in the refrigerator for up to two months. Then, defrost in the fridge and bake in the oven at 430 °F (220 °C) while covered with aluminum foil.
