For kumpir, you need to choose large-sized potatoes. One potato for each serving. Wash the potatoes well, wrap in foil, and bake in the oven until tender. I baked at 180 degrees for almost 2 hours. The time depends on the potatoes and their size, after 40 minutes you can check the readiness. Then, after the potatoes are ready, you need to cut the potatoes from the middle to the crust. After we have made a small incision, we need to mash the flesh of the potato, add a little (grated) Holland cheese and butter. And inside you can add fish, lettuce, carrots, corn, everything that is, I added a salad. DON'T FORGET TO SUBSCRIBE.
