Safeway has been periodically having tri-tip roast on sale for something like $3-4 a lb. Pretty cheap, all in all. It's not the tastiest of cuts, specially the Safeway brand which emphasizes tenderness over flavor, so I looked for a recipe that would infuse some flavor in it. This recipe for Hoisin-Marinated Tri-Tip Roast sounded pretty good and it got good reviews. Alas, it wasn't as good as I'd hoped. The outside of the meat was nicely caramelized and very tasty, but the flavor didn't make it all the way through. I don't think I'd bother making it again.
