Blue Cheese Steak Sauce
It's not brilliant, and it ain't gourmet, but it does the job.

Blue Cheese Steak Sauce
A serviceable blue cheese sauce. For steak and such.

Boil the alcohol to reduce by about half.
Add the sour cream and mayonnaise and heat gently.
Add the meat juices and a dash of Worcestershire sauce, add half the cheese and stir until melted.
Add the rest of the cheese off the heat so it doesn't melt away completely and leaves a little texture.
Stir in the herbs.
Pour over your steak. Or such.
Best not to boil it lest it split.
