Beef Stroganoff
Cut the beef across the grain into thin strips 5 mm thick and 4 cm long. Slice the onion into thin half-rings and sauté in butter until softened, 6–7 minutes; transfer to a bowl. Heat the oil over high heat and fry the meat in two batches for 2–3 minutes each, so that it browns rather than stews. Return the onion and all the meat, add the flour, and stir. Add the sour cream, tomato paste, mustard, and hot water; season with salt and pepper and heat over low heat for 5–7 minutes until a thick sauce forms, avoiding a vigorous boil.

Preheat the oven to 190 °C. Core the apples, cut them into 2 cm cubes, mix with the berries, one-third of the sugar, and cinnamon, and place in a baking dish. For the crumble, mix the rolled oats, flour, and remaining sugar, add the cold butter in cubes, and rub with your fingers until you have large, moist crumbs. Scatter the crumble evenly over the fruit without pressing it down. Bake for 30–35 minutes, until the top is browned and the fruit juices are bubbling around the edges.
