Ingredients:
- 3.25 tablespoons beef drippings (fond), ghee, or bacon fat
- 1 teaspoon all-purpose flour (or 1/2 teaspoon cornstarch/arrowroot)
- 2.5 cups concentrated beef stock (dark, low-sodium preferred, or beef base mixed according to directions)
- 0.5 teaspoon salt (to taste)
- 1/4 teaspoon ground black pepper (to taste)
Instructions:
- If using natural pan drippings, skim off any excess liquid/solids, leaving 3.25 tablespoons of fat and fond in the roasting pan. Alternatively, melt the designated fat (ghee, bacon fat, or drippings) in a medium saucepan over medium heat.
- Whisk the flour (or cornstarch) into the melted fat until a thin, uniform roux forms. Cook for 1 minute, ensuring the mixture smells nutty but does not burn.
- Slowly pour the concentrated beef stock into the pan. Immediately scrape up all the caramelized dark bits (the fond) stuck to the bottom of the pan using a wooden spoon. Bring the liquid to a gentle simmer, whisking constantly to dissolve the roux and eliminate lumps.
- Allow the jus to simmer gently for 5–7 minutes. It should reduce slightly and thicken to a thin, silky consistency (it should not be thick like gravy). Season generously with salt and pepper to taste. Serve immediately.
