How to make a basic roux (1:1 butter to flour) and cook out the raw flour taste

Whisk equal weights of butter and flour into a paste and cook on low heat for about 5 minutes to remove raw flour flavor.

The chef uses 75 g unsalted butter and 75 g unbleached white flour, whisking into a paste. He stresses cooking it on low heat for about five minutes so the flour taste doesn’t carry into the finished sauce.
