Steak tips with red wine pan sauce for two

We tried a recipe from an America’s Test Kitchen Dinner for Two Magazine; this same recipe is available in The Complete Cooking For Two Cookbook https://www.amazon.com/dp/1936493837/ref=cm_sw_r_cp_api_HdgAyb004ATQN

We served these beef tips over homemade mashed potatoes, although we used only 4 medium Yukons: http://piglettedc.tumblr.com/post/133996295246/simple-mashed-potatoes-this-is-a-recipe-from-my (Dec. 2016)
