we love to cook silverside just like you did but in our DREAM POT - its a thermal cooker nd often there are inexpensive models at Aldi but they are beaut
Just put all into the saucepan - simmer for 30 minutes then into thermal cooker ( no hat or power connected) for 8 hours - cook while you drive
we also love it baked - wash the beef - dry it and coat with smoked paprika,garlic powder and ground pepper
we bake ours wrapped in aluminum foil in our Cobb but its just as easy in the oven - about 2 hrs at 180 c internal temp 75c
