Tips:The method of dry-stirring is to cut the potato slices thinly, soak them in water and then fry them. Use a large non-stick spoon, which will not stick to the pan. The oil is more delicious. If it's not a non-stick large spoon, it will stick to the pan easily. You can add a little water, but it's better if it's dry-fried.
The beef can be boiled in a pressure cooker for half an hour if you have time. The soup is used to make noodles, and the beef is frozen or refrigerated for storage. It is very convenient to eat.
