After applying olive oil and seasoning to the roast, you are going to set it directly on the grates after your smoker is heated to 225º. The rule of thumb here is roughly 30 minutes per pound. But I would encourage you to use a meat probe during your entire cook. That way you will hit the perfect temp and never have to open the smoker during your cook. Insert the probe into the thickest part of the meat and then pull your roast at 120º. After resting and searing, your roast will be at 125º....a perfect medium rare.
Zip Sauce is a regional specialty. It was first used in the 1940's by Lelli's Inn, an Italian restaurant in Detroit. It's a simple, butter-based sauce that takes inexpensive cuts of beef to a whole new level. Splash some on your smoked top round roast and you and your guests are in for a total drool fest! Pass the bibs, please.

- While the roast is cooking, combine all Zip Sauce ingredients in a small saucepan over medium heat. Bring to a bare simmer, whisking constantly. Remove from heat and cover to keep warm until ready to serve.
