Step 1

Cook the onions in the 3 tablespoons butter in a skillet over medium heat for a few minutes. When the onions are brown, turn off the burner temporarily so you won't ignite your kitchen. Or yourself.

Step 2

Pour in the whiskey. As soon as it evaporates, turn the burner on medium-high heat and pour in the beef stock. Add salt and freshly ground black pepper to taste, then allow the mixture to bubble up and reduce by half.

Step 3

Whisk in the remaining tablespoon of butter, then reduce the heat to low. Whisk in 1/4 cup to 1/2 cup cream, according to your taste. Allow the sauce to simmer and thicken for a few minutes.

Step 4

Serve with beef, baby!
