Ingredient Notes & Substitutions
What is a Tri Tip Roast?
A tri-tip roast is also called a bottom sirloin roast and is a flavorful cut of beef taken from the bottom of the beef sirloin and is great for a variety of cooking methods. Tri-tip roasts are not typically high in fat but have just enough to add flavor. They taste great when they are grilled, roasted, or slow-cooked.
I like tri-tip roasts because they are lower in fat than most cuts of beef that you would typically slow cook, yet you can still turn it into shredded beef. Tri-tip steak or roast is easier to find on the west coast, but you can get them on the east coast too. Check with your local grocery store or butcher. They are also available from time to time from Butcherbox.
Substitutes for Tri Tip Roast
If you can’t find a tri-tip roast, you can still make this recipe. Here are a few suggestions for alternatives to tri-tip: sirloin tip roast, chuck roast, beef brisket, or bottom round roast.
The Best Red Wine to Use for Slow Cooking
The best red wine to use in cooking is a full-bodied wine such as cabernet sauvignon. It doesn’t have to be overly expensive, but choose one that is also acceptable to drink.
Substitutes For Red Wine
Red wine adds a wonderful flavor to this recipe but can be easily substituted one for one with beef broth, beef stock, chicken broth or chicken stock.
