Lay the beef and sprinkle flour on both sides using a tea strainer. Cut them into bite sized pieces and thinly slice the onion.
Melt butter in a pan, and fry the onion until wilted. Move it over to one side and put the beef in the empty space. Fry it all together.
Add the canned mushrooms juice and all, the soup stock, and milk. Boil until everything thickens.
Enjoy with rice in the morning.
Story Behind this Recipe
I hate doing things which take time and effort so I made it as simple as I could.
Taste it when it's done. If it's too strong, add milk, if it's weak, add salt. The can of mushrooms contained 100 ml of juice and had a net weight of 100 g. Adjust the amount of milk etc. depending on the size of the can you use.
