Rebecca is totally right. Citrus fruit is a great antidote to winter blues. I had a lot of clementines and a burning desire to make cake - Nigella's clementine cake. And then it seemed like fun to poke a sparkler in it. Just for extra joy.
Though I do have a slightly chequered sparkler past to confess to. Way back in the dawn of the new Millennium (in the era before children) we were planning a party for New Year's Eve. It needed some kind of special centrepiece. Something to mark the occasion. As a nation, the Milennium Dome was deemed the appropriate choice.
Good enough for the nation? It must be good enough for us. So we recreated it in the living room, in the form of a Baked Alaska (we were so damn classy in those days). And for those big yellow struts? You guessed it, whacking great sparklers. To be lit on the first stroke of midnight on the dawn of a new century.
Which is how we came to spend the first half hour of 2000 on the front lawn of the house, with all the doors and windows open, trying to get rid of the noxious smoke that had filled the whole of downstairs. Crying with champagne fueled laughter. Who knew you weren't meant to use outdoor sparklers inside?
Thankfully, the new millennium has brought with it the advent of the indoor sparkler.
