Hey Kitty
You have now touched on the other subject near and dear to my heart - food! Good recipe. Might want to also try marinading beef in a combo of red wine, garlic, carrot, onion, celery and thyme (or other hardy herb) pat dry and then brown. Also for plating considerations cut large cubes. Fry more onions and garlic, place in meat and use more wine and the marinade (sans aromatics) for liquid. As pointed out by Kitty do not boil but simmer. About an hr or so into the cooking process (depending on amount of meat) add button onions and mushrooms. Thicken with slurry or with cream serve with boiled potatoes or broad noodles or crusty bread and crispy side salad.
Should time the cooking to coincide with trainer workout
