The rillettes can be refrigerated for up to 1 month. Keep the meat covered with a layer of fat.
Rendered pork fat is available from farmers' markets or from prairiepridefarmminnesota.foodoro.com.
Rich pork rillettes will pair well with a strong whiskey-based cocktail, like an old-fashioned. The dish would also be a nice match for wines that have good tannins to balance out the fat. Try a Cahors from the southwest of France.
