Tasso is a spiced, smoked pork used to flavor many of Louisiana's hallmark dishes. Coffee gives this thin gravy an incredible depth of flavor.
Melt butter in a skillet; add tasso, and saute until browned. Whisk in flour, and cook, whisking constantly, until lightly browned. Whisk in coffee and broth; simmer, whisking occasionally, 20 minutes. Stir in thyme, salt, and pepper.
