Wash the potatoes and cut into thick slices. Clean the beans and cut into 2.5 cm long pieces (I also use frozen delicatessen beans).
Heat the butter and oil in a pan over a high temperature. Add the chili peppers, cumin, turmeric and garam masala to the pan. Press the garlic into the pan through the press. Fry everything while stirring for 30 seconds. Add the potatoes to the pan, season with salt and stir until coated with the fat. Steam for 15 minutes.
Now add the beans and cook for about 15 minutes with the lid closed and at medium heat. Stir occasionally. Do a chopstick test on the potatoes.
In addition, I serve small meatballs and add the same spices as in the main course to match the taste.
