Your best gravy secrets

This is my recipe for sage gravy from when I was the saucier at Canyon Ranch. It's a health spa, so if you're not counting calories, you can boost the butter. To help deepen the flavor, saute the onions until they're quite dark, but not burned.

That is real close to what I used to make a crock-pot of beef stew this morning.
Waiting for it to be done, stopped at the store and grabbed a fresh loaf of Italian bread.
Stew should be super good, did not use a roast, instead cut up some sirloin steaks that were about 1" thick, I got from the local slaughter house.
