Steve Puleo, executive chef at Riverside Tavern, says he created the recipe when Grady's first opened. At that time it was a Regas restaurant. It is now on the menu at Chop House, where Puleo also was a chef at one time.
2 pounds fresh button mushrooms
Water, enough to cover in a kettle
Fill a clean, sanitized sink halfway with water. Pour mushrooms in and agitate until all mushrooms have been thoroughly cleaned.
In a kettle, bring to a boil enough water to cover the mushrooms. When water is boiling, add mushrooms and cook until water returns to a boil. Remove from heat and pour mushrooms through a colander. (This just poaches the mushrooms.)
3 ounces butter
6 tablespoons onions, sliced
1 cup burgundy wine
1 tablespoon beef base (bouillon)
2 teaspoons white pepper
4 teaspoons granulated garlic
12 tablespoons sherry
In kettle melt butter; add onions and saute.
