BS Fries

Method

Preparing the Prime Rib

1

Season the Roast

Rub the prime rib roast with olive oil, salt, black pepper, garlic powder, onion powder, and rosemary. Ensure it is evenly coated.

2

Smoke the Roast

Preheat your smoker to 225°F (107°C). Place the seasoned prime rib in the smoker and cook until the internal temperature reaches 130°F (54°C) for medium-rare, about 4-5 hours.

3

Rest the Roast

Remove the prime rib from the smoker and allow it to rest for at least 20-30 minutes before slicing.

Making the Au Jus

4

Combine Ingredients

In a saucepan, combine beef broth, red wine, and Worcestershire sauce. Bring to a simmer over medium heat.

5

Thicken the Jus

Mix cornstarch and water in a small bowl, then whisk into the simmering broth. Cook until slightly thickened, about 5 minutes. Season with salt and pepper to taste.

Preparing Horseradish Sauce

6

Mix Ingredients

In a bowl, combine prepared horseradish, sour cream, lemon juice, and salt. Mix well and refrigerate until ready to serve.

Making BS Fries

7

Cut Potatoes

Cut russet potatoes into fries and soak them in cold water for at least 30 minutes to remove excess starch.

8

Fry the Potatoes

Heat vegetable oil in a deep fryer or large pot to 350°F (175°C). Fry the potatoes in batches until golden brown and crispy, about 5-7 minutes. Drain on paper towels and season with salt.
