A tried & tested English favourite. Great 'confort food'. Pair it with a good English beer from Fullers or a Guinness or a Zinfandel:
Sprinkle flour over diced beef; toss till beef cubes are floured.
Add oil to pan sauté beef till rare (about 30 seconds). Add the add mushroom quarters.
Simmer 5 minutes more, then add ale & then gravy or demi glace.
Cook over low heat for 20 minutes add sea salt and/or ground white pepper to taste, but be careful; do not over season.
Put in your favorite four bowls and top with mashed russet potatoes or pie crust.
