I think baking is very rewarding, and if you follow a good recipe, you will get success.

My son is a tree surgeon and gets me a lovely tree. I like to put it up early, as I can't wait for Christmas. We dress it with decorations that have been in the family for years.

I am a bit of a mother hen at Christmas! I always prepare in advance. It is the only way; otherwise, it can be really daunting.

Making your Christmas cake in September is perfect, as too fresh a cake crumbles when cut.

All my grandchildren bake. On a Saturday, Annabel's boys, Louis and Toby, always bake. Louis makes a chocolate cake, Toby makes banana or lemon drizzle. They're 12 and 10, and they can do it totally on their own. My son's twin girls, Abby and Grace, are 14; they make birthday cakes and like to do it on their own with Mum out of the way.

I am not great at computers. If I were to try shopping through Google, I'd end up with 33 vests.

I still think it's essential for a parent to cook with their children. Weighing out the ingredients and learning where the food comes from is educational, but it also helps to place meal times at the heart of family life. We never had dinner in front of the TV.

Having children is the greatest thing that can happen to you as a husband and wife. They are infuriating at times when they're little, but on the whole, they're such a joy. I don't think I was the most brilliant mother when they were young. I had quite a bit of help because I was working and I enjoyed my work.

To be able to walk out the door when you come home from a job and wander into the garden to do a bit of watering gives you time to be creative in your mind.

The very best hotel I've stayed in is the Intercontinental on Park Lane. We went there for the Chelsea Flower Show a few years ago, and it was sheer luxury. Everybody had a smile on their face. I came home and changed all my pillows because the hotel ones were so beautiful.

When I was paralysed by polio at 13, I went into an isolation hospital and couldn't sit up, so I only took liquid food from spouted cups which the masked nurses would bring in and feed to me. I saw my parents only through glass; we couldn't touch.

I mainly cook British food with a few things I've had on my holidays. I went to the Canary Islands a few years ago, and we had all sorts of different mushrooms on brioche with pancetta on top, and it was delicious. I had it most days for lunch, so I thought, 'I'll do that when I get back,' and now it's in my cookbook, an absolute favourite.
