Ah.... but give us some more information.

Is it baked or broiled?

At what temperature if baked?

How long do you cook it? Or.... what color should it be?

How thick should the flower be on the cookie sheet ?

I have to confess that we have been using the savoie's dry roux at my house. Ever since we started eating healthy my stomach can't take the grease of a traditional roux. We brown our meat in black iron pots with the holy trinity, then put all of that in boiling water with the dry roux and it comes out good. Maybe not quite as good as a traditional roux but i won't be in the bathroom all night after eating.

The beginning of a gumbo I cooked last week. I was supposed to take some progress pics, but forgot. That's a real gumbo. Not that brown soup them boys from TX cook!

yes please share, its easy for the guy who knows how, but I have never even heard of this method, much less know anyone else who has.

distribute 2 - 6 cups of flour evenly over the dry bottom of a big iron skillet or heavy Dutch oven and put it in a 400 degree oven for about an hour. Stir it about every 15 minutes or so to brown evenly.
Let cool and store in glass jar. To Use: Mix equal parts dry roux and water till smooth. Add to gumbo, soups, and gravies for thickening. Perfect! And you haven't used any grease at all. alternatively, you can put the desired amount of flour on a baking sheet and bake it at 350 for about 25 to 60 minutes. You could use the browned flour as is or add oil and make a paste

thanks, im going to give it a try next time I need roux.

for the baking pan, how thick is too thick to brown it when spreading out the flour? 1/16" ? 1/8" ?

You can go 1/4 - 3/8" easy just stir it around a few times during cooking.

My Roux See Video on how I make mine
 

I make my roux with equal parts flower and oil. I add my onions once the color is where I want it to be. See the video on how I make my roux
