Name: Herbed Roast Beef with Horseradish Sauce and Yorkshire Pudding
Ingredients: 1 x 3-rib standing rib roast (about 7 lbs, 3.2 kg); ¼ cup (60 ml) Dijon-style mustard; 3 cloves garlic, finely chopped; ¾ cup (180 ml) chopped fresh parsley; 2 tbsp (30 ml) olive oil; 2 tsp (10 ml) dried thyme; 2 tsp (10 ml) dried rosemary; salt and freshly ground pepper to taste

Why it works: Thyme and rosemary match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 1,340 recipes mention both. Both carry beta-phellandrene, which smells minty, terpene. The science ↓

Timeabout 3½ hours

Ingredients

1 x 3-rib standing rib roast (about 7 lbs, 3.2 kg)
¼ cup (60 ml) Dijon-style mustard
3 cloves garlic, finely chopped
¾ cup (180 ml) chopped fresh parsley
2 tbsp (30 ml) olive oil
2 tsp (10 ml) dried thyme
2 tsp (10 ml) dried rosemary
salt and freshly ground pepper to taste

Directions

Age and prepare

For best results, age the beef for 4 to 7 days. Refrigerate uncovered for 4 to 7 days.
Unwrap the roast, dry it thoroughly with paper towels, and place it on a wire rack set over a pan lined with paper towels.
Before cooking, trim off any parts that are completely dehydrated.
Whether you age the beef or not, allow the roast to sit at room temperature for 3 to 4 hours before cooking.
Tie segments of cooking twine around the roast, between and parallel to the ribs, to prevent the outer layer of meat from separating from the rest of the roast during cooking.

Season and roast

Place the roast rib-side down on a wire rack in a large roasting pan.
Spread the top and sides with the mustard.
Combine the remaining ingredients and spread over the mustard.
Place in a preheated 200°F (95°C) oven until the internal temperature reaches 130°F (55°C) for medium-rare, about 3½ hours, or 30 minutes per pound.

Rest, carve and serve

Remove from the oven and let stand 30 to 60 minutes before serving.
Reserve the drippings for the Yorkshire pudding.
To carve, stand the roast up so the bones are pointing upward.
Remove the twine and slide a long carving knife along the ribs to separate the meat from the bones.
Place cut-side down and cut across the grain into thick slices.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Standing rib roast: Is the main protein, cooked slowly to a tender, evenly pink medium-rare centre.
Dijon-style mustard: Adds sharp flavour and helps the herb coating adhere to the meat's surface.
Garlic: Contributes pungent aroma that mellows during the long, low roast.
Fresh parsley: Adds fresh, green herbal flavour and colour to the crust.
Olive oil: Carries the herbs and garlic and helps the surface brown.
Dried thyme and rosemary: Add earthy, aromatic herb flavour that perfumes the roast's surface.

The step that matters

Roast low and check the internal temperature. Cooking at 200°F gives even doneness, but the roast keeps cooking as it rests. Pulling it at 130°F and checking with a thermometer, rather than relying on time alone, prevents overcooking the grey outer layers.
