Got me there....I have used a package when desperate and then dressed it up with spices, onion, etc....but without the pan drippings I have no good response, but I will be interested to see what others offer.
onion, celery, sliced carrots, potato optional, butter in a metal pan. broil until veggies are carmelized, add water or broth to pan stirring and scraping the bits that stuck to the bottom. run thru a food mill or food processor and simmer until thickened. salt and pepper to taste!
i dont think you can have that..but you know what i always have on hand is kitchen bouquet..if you fried up some onions and mushrooms and tossed in that for good measure you would have some brown gravy.
