We haven't had a roast beef for a long time and since there was a perfect little sirloin tip roast on special, I picked it up. I seasoned it with Montreal Steak Spice over all the outside. Inserted a meat thermometer and put in the oven at 300ºF. The mashed potatoes were ordinary and the vegetables were steamed and finished in olive oil. I'm getting much better at that, not over cooking them. When the roast was at 150ºF in the center I took it out and set it to rest under foil.
The gravy was made in the roasting pan. 2 teaspoons of flour cooked off in a little butter then stock till it's the right consistency. It should have enough salt from the roast so it only needs a dash of Worcestershire Sauce.
Horseradish is the condiment and it was a wonderful meal.
