Ham, egg and chips

I'm not sure how long it takes for something to become a Christmas tradition. The word suggests a custom that has been handed down through the generations, rather than something that has become habit after two or three years. But when we first had children we went out of our way to forge our own Christmas traditions. Although we both wanted to honour our own childhoods, we also wanted to put our stamp on the day. So far we have three traditions that we love celebrating.
The first is that before the girls' bed time on Christmas Eve, we all open a snuggly new pair of pyjamas, so we wake up looking our best for stocking-opening the next morning. This year the girls have got onesies (snow leopard themed, no less) and although I tried one on, sanity prevailed and I opted for some cosy M&S red flannel ones instead.
And then we eat Yorkshire Puddings with our turkey. Proof that even Christmas lunch can be improved upon.
My favourite tradition is the ham, egg and chips we eat for Boxing Day lunch. Its simplicity is the perfect foil to Christmas Day's lavishness and it is so low-energy you don't really even have to think about it. If you are time-pressed then you can buy sliced ham off the bone from your butcher or a good deli and serve it with two fried eggs per person and a handful of chips (oven or homemade). HP sauce is obligatory. As is mustard.
It is much cheaper to make your own ham. My butcher saved me a small piece of gammon (about 1.5kg) that I will simmer in cranberry and apple juice in a large saucepan for two hours with a cinnamon stick and a halved onion. Before finishing it off in the oven, studded with cloves and glazed with leftover cranberry sauce. The ham is a Nigella recipe but you can cook (or buy it) any which way you choose.
And on that note, Hammy Christmas.
