Making roux can sometimes turn into a mini social event in itself. Friends will often come over and visit with you while you're making a roux. Put some Zydeco music on the box and open the windows. A couple of cold beers and a few smokes later the roux is done and the party is just starting. Creole life is a good life.
Some folks make their roux in the microwave.
I make mind the old fashioned way. Standing and stirring till the roux is the color of fudge or a Hershey bar. Some make a lighter roux. I can remember eating many a piece of roux from a saucer in the refrigerator when coming home late at night after too many beers at one of the honky tonks. The chunks of roux looked just like chunks of fudge candy.
