Tri Tip is something you can not find everywhere - if you dont see it in the store, ask the butchers at the glass counter as they may have some in the back. Also, a small family style butcher shop may be able to get you some. 

This meat is super easy to cook - even with a variety of ways to cook it. Most sizes serve a family of 4-5 and its great next day sliced cold for a sandwich or reheated in the microwave for lunch. Something about smoked meat tastes great eating it next day chilled by itself or on a sandwich that my family enjoys. 

I will keep it simple - its a forgotten piece of meat in the shape of a triangle. It has grain going one way at the point and near the back larger section the grain switches direction. 

I did a recent cook with a Tri Tip on the amazing Kudu Grill and here is the finished cook before letting it rest on my wood cutting board of how I will slice it up.

When you get it at the store or butcher, You can save the meat for later...
