It was January and my mother in law gave me a Gressingham Duck left over from her Christmas Fayre. I decided to roast it for a change and as a duck is so fatty, caught the fat in a tray as the duck cooked on a rack. The fat from the duck was full of flavour and as the duck roasted in the oven for a few hours I drained out the fat every hour so it didn't burn. I decided to use the fat from the duck to roast the potatoes and if I say so myself, these were the best tasting roasties I have ever made!
