Once the pork has had 20 mins, turn the oven down to 180C/160C fan/gas 4. Remove the pan from the oven and briefly remove the pork to a plate, then brush with the mustard, avoiding the skin. Stir the onions, then add the potatoes, stirring well to coat. Pour in the chicken stock, then place the pork on top. Return to the oven for another 40 mins.
