All you need to make a roux is fat and flour. Choose your fat based on personal preference — clarified butter, vegetable oil, olive oil or even bacon grease are all appropriate options.

Can a roux split?

If it's too cold it hardens the butter, and if it's too hot it can separate the roux. The way roux thickens a liquid is by the starch molecules in the flour absorb the liquid and expand, becoming slightly gelatinous, which creates the effect of thickening the sauce.

Should Roux smell like burnt popcorn?

If you see dark specks and smell burnt popcorn, you may have burned the roux. If you burn the roux, you must dump it, clean the pot and start over. Anything you add to a burnt roux will be ruined. If you think you burned the roux, but you didn't, that is a good dark brown roux.
