It's worth purchasing a meat thermometer for this recipe. We used an instant-read version, but a standard one would work equally well. Cook the roast to 180° to 185° for incredibly tender but sliceable meat, making a pretty holiday presentation. Pableaux likes to cook the roast an hour or so longer (to about 190°) for meat that falls apart.
1 (5- to 6-lb.) bone-in pork shoulder roast
10 garlic cloves, halved
5 teaspoons Cajun seasoning
2 tablespoons vegetable oil
3 medium onions, halved and sliced
3 celery ribs, chopped
1 (14.5-oz.) can low-sodium chicken broth
3 tablespoons all-purpose flour
5 tablespoons cold water
Garnishes: red grapes, sliced pears, collard green leaves, persimmons
How to Make It
Preheat oven to 325°. Make 20 small, deep cuts in roast, and insert garlic pieces. Tie roast with kitchen string, securing at 2-inch intervals. Rub Cajun seasoning onto roast.
Cook roast in hot oil in a large heavy skillet over high heat 2 minutes on all sides or until browned. Remove from skillet. Reduce heat to medium. Add onions and celery to skillet; cook, stirring frequently, 5 to 8 minutes or until tender. Place onion mixture in a roasting pan; top with roast. Add broth to pan. Cover loosely with heavy-duty aluminum foil.
Bake at 325° for 3 1/2 to 4 hours or until a meat thermometer inserted into thickest portion registers 180° to 185°. Remove roast from pan; cover with foil, and let stand 20 minutes before slicing.
Pour pan drippings through a wire-mesh strainer into a measuring cup to equal 2 cups, adding additional broth or water, if necessary. Discard solids.
Whisk together 3 Tbsp. flour and 5 Tbsp. cold water in a medium saucepan. Whisk in pan drippings. Cook, whisking often, over medium-high heat 6 to 7 minutes or until thickened. Serve with pork. Garnish, if desired.
