Pro Tips
• For an even deeper flavor, season the lamb shanks with salt and pepper and sear them in the hot oil on all sides before adding the garlic. Remove the shanks, then proceed with the recipe, adding them back in at step 4.
• If you prefer a thicker gravy, create a slurry by mixing 1 tablespoon of cornstarch with 2 tablespoons of cold water. Whisk this into the simmering sauce at the end until it reaches your desired consistency.
• Use a quality Ruby Port for this recipe. Its fruity, robust character is essential for the sauce’s flavor profile. Avoid using salted ‘cooking wine’.
• These lamb shanks are divine served over creamy polenta, mashed potatoes, or egg noodles to soak up every last drop of the delicious gravy.
