This is a very elegant dinner party meal, it looks and smells wonderful and it tastes unbelievable with the truffle oil in the parsnip mash and the port berry sauce is very good. It is a little time consuming as there is a little prep time, chopping vegetables and also the cooking down of the sauce, but it is well worth it for the end result. My whole family thought it was yummo and kept raving about both the duck with the sauce and how much they loved the parsnip mash, I had gone up to my mum's house for dinner and made this so it was tested out on many and a success all round. I am listing the recipe below for 2 people as I wrote down the ingredients I used when just making for myself and hubby, because it is hard to reduce the sauce amounts without affecting the flavour the sauce would be enough for 4-6 people. So you could cook extra breasts and then just up the amount of mash ingredients.
