- Whisk in flour, a little at a time and cook, whisking constantly, until roux becomes smooth and thick. Continue to cook, constantly stirring with wooden spoon and reaching all over bottom of pan, until roux darkens to desired color. Chef’s Note: Be careful not to produce specs of black. Roux must remain an even color throughout process. If specs appear, start over.
- For dark brown roux, cook mixture an additional 35 to 45 minutes. It should resemble dark chocolate when ready. Remove dark roux from pan and cool completely.
