I made my first roux yesterday!  It was for a sauce to go with the steak I cooked, and I did it all on my own, with nary a recipe.  I had one in my head, but it was rather cloudy and not too informative beyond having some sort of fat in a hot pan, cooking a bit of flour in that, then bulking it out with a liquid and seasoning with spices.  But you guys, I did it and it worked and it’s delicious!  Well, it was delicious for dinner last night and lunch today.
