Ingredient

Andouille sausage

Coarse smoked pork sausage, heavily seasoned with garlic and cayenne — the Louisiana version, which is a different animal from the French tripe sausage of the same name. Already cooked, so it is browned for flavour rather than cooked through.

Sourcing
American butchers and Cajun specialists. A smoked kielbasa with added cayenne is the usual stand-in and is noticeably milder.
Varieties
Louisiana, Cajun, French (tripe)
Quality cues
Deep mahogany from the smoke, firm, coarsely ground with visible fat.
Substitutions
Smoked kielbasa with cayenne, Chorizo, for a different spice, Smoked pork sausage
Storage
Refrigerate; it freezes well and slices more neatly half-frozen.
Shelf life
2 weeks refrigerated, 6 months frozen
