Steak sauce with mushrooms and shallots

Ingredients:
Shallots - finely diced
Mushroom - sliced
Red wine
Salt
Pepper
Butter
Standard flour (optional)

This is a great sauce for pan-fried steak and mashed potatoes. By the way, you can find the guide to cooking a steak here. After you have finished frying your steak, set it aside and cover with something like tinfoil to keep warm. In the same pan leave the steak juices, and scrape off some of the bits that are stuck to the pan as these will add a lot of yummy flavour. Add the shallots, and mushrooms, and saute them in some red wine on high heat. Bring to boil and reduce heat to medium. Add salt and pepper to taste. You can also add a touch of standard flour to help thicken up the sauce. Saute until the shallots and mushrooms become brown and soft. Take the pan off the heat and whisk in a small nob of butter. Done.

Pour the sauce over your steak and potatoes and eat! You can experiment with this recipe by trying different herbs, and also using sherry or port instead of wine.
