It is quite a fiddly recipe and can get technical in parts, but it is definitely worth the effort when you eat it.
Luckily, my husband Markham is the one that is responsible for cooking it, I try to help him out a little bit with the preparation, but I am just a kitchen hand at best.
The big thing with it is it needs to be cooked just right, so it can be high-stress getting the timing right to take it out of the oven.
We prefer to have it cooked medium - I don't like it too blue, but if you overcook it, it's a disaster.
We tend to rotate our Christmases, one year we'll have it with my family in Wanganui, the following year we spend it with Markham's family in Dunedin.
It doesn't matter where we go, there are always lots of kids around.
We have a big extended family so Christmas Day is always a busy affair with lots of noise - mainly from my kids, Kiana and Aria.
