Thanks to this Stilton sauce recipe from the Barefoot Contessa, I had what I was looking for. Now I just have to figure out how to use the yummy leftovers...would love to hear your ideas in the comments below.
Blue Cheese Sauce
The recipe makes a generous 2 cups or so of sauce, so you might consider cutting it in half if you are just amkinf for a steak or two.
4 ounces Stilton cheese, crumbled
8 ounces cream cheese, at room temperature
1/2 cup good mayonnaise
1/2 cup sour cream
1 tablespoon chopped scallions, white and green parts
1 teaspoon kosher salt
1/2 teaspoon freshly ground black pepper
1/4 teaspoon Worcestershire sauce
Place the Stilton in the bowl of a food processor fitted with a steel blade and blend until finely minced. Add the cream cheese, mayonnaise, sour cream, scallions, salt, pepper, and Worcestershire sauce. Process until smooth. Serve at room temperature.
