Combine the beef, arrowroot flour, salt and pepper; toss to coat. In a large skillet, add 1 tbsp oil and brown beef in batches, about 4-5 minutes per side. Or brown directly in your instant pot on the sauté mode. Once brown take out and set aside.
Meanwhile chop turnip, carrots, garlic, onion, and celery. Add 1 tbsp olive oil or lard and the chopped vegetables in the instant pot and stir. Cook for about 5 minutes on the sauté mode. Alternatively sauté in a skillet.
Add the remaining ingredients and stir well to the instant pot. Return the beef to the instant pot as well. If using a slow cooker, transfer browned meat, chopped vegetables, and remaining ingredients to the slow cooker.
Cover and cook on low for 8-10 hours or until beef is tender. You can also cook on high for 4 hours.
