I've been thinking about food. Or, to be more accurate, I've been thinking about cooking and baking and how I feel about these activities - and about the fact that this morning I spent about an hour reading a recipe book. (I was given a pile of wonderful Ottolenghi books for Christmas; they're already full of paper markers and a list to tell me where exciting-looking things are.) It is perhaps a clue to my attitude that I then felt compelled to clean the bath - for a small inner voice told me that I'd been wasting time, sitting in my cosy living-room looking at the birds on the snowy feeder and reading about food. And cooking.

I love food. I'm what you would well call fussy, in that I like interesting and well-cooked food, and that there are things I body-swerve with increasing dedication: cream, fatty foods, shellfish, anything that will lie weightily in my digestive system long after I'd prefer to have forgotten about it. My mother, and now my sister, have long mocked my preference for green tea. But because I love good food, I try to produce same - and on the whole I would say I succeed. The creation on the right is one I recently enjoyed - venison fillet accompanied by freekeh pilaff and garlic yogurt - and I usually say that no-one who likes eating should be incapable of producing a decent meal.

But even after almost 44 years of being responsible for making the meals in my own home, I still feel it's not really me. I have the sense that I'm a sort of dilettante cook, playing at it without having acquired the basic skills or even the right equipment. Baking is even worse. My closest pal throws pastry together without a thought and uses it to entertain my grandchildren; she may never know (unless she reads this) how much awe I hold her in for this simple act. My Christmas cake is the best I've ever eaten, but since I stopped making children's birthday cakes it's the only cake I ever make - and more or less the only cake I eat, come to that.

So when I refer to myself as a Domestic Goddess, you should know that I do so in the spirit of deepest irony. Cooking - and the odd bit of baking - gets fitted in round the rest of my life even if the results are totally toothsome, and there's always this feeling that I'm in the same boat as the monkeys writing a Shakespeare play. Or something. My attitude to eating, I've decided, has hardened over the years. I shall never again, for example, eat a pizza - because you have to climb a Munro to use up the resulting calories. And I shall leave you with one final, devastating truth:

Life is too short to eat a custard cream.
