Cook until tender but still slightly firm in the centre, approximately 8-10 minutes. Drain the water and toss in the colander to gently break up edges. Leave in the colander to steam for a few minutes

Remove the steaks from the oven and set aside to rest for 4 minutes. Serve with the potatoes and mustards
