The steak you bought, washed, put in a storage bag, and smashed with a meat hammer
Sprinkle black pepper on both sides, salt, and pour in one-third of the red wine (not cheap, don't use ice wine, otherwise it will be too distressed). Marinate for more than half an hour.
Put the olive oil in the pot, pour the chopped sweet potato pieces, slowly cook over low heat, pan out, cut cucumber and lemon
Put a piece of butter, put it into the steak after it has been cooked, fry it for 2 minutes, turn it over, fry it for 2 minutes, then turn it over for 2 minutes.
Pour the juice of the steak into the pot, put a little cornmeal to thicken it, and do the baking, which is not the one that licks the cornmeal. After the soup is thickened, it is poured on the steak.
