Stating the bleeding obvious

At risk of stating what should have already occured to anyone with an ounce of logic, never ever go food shopping when you're hungry and tired.

I didn't have much of a lunch today because all I had in the fridge was some hummous, which I ate with a slice of untoasted wholemeal pitta bread. I was on my way out the door to a tasting, and was running late, so had no time to prepare anything more satisfying and nutritious (although hummous and wholemeal pitta makes a good snack – it keeps you full for a fair while and has lots of fibre).

So – another big tasting. Bibendum, one of the UK's biggest wine merchants, holds an annual tasting – and it's vast. They'd hired out part of the Royal Academy complex off Piccadilly. There must have been several hundred wine producers there – all of them with at least a couple of wines each. Of course I didn't taste everything there. In fact I spent most of the time doing interviews with wine buyers and sommeliers – I'm behind schedule on a couple of deadlines, both of which I need to meet before I head off to Italy early on Friday.

By the time I left, I was feeling tired and emotional, and for once I'm not using those words to mean that I was drunk. But I also knew there was nothing in the house for dinner. So I stopped into an M&S to grab something to cook tonight. But because I was so tired and because I hadn't eaten well, my blood sugar had dipped, and all I wanted to do was to grab one of the delicious-looking pastries. Either that or slump down in a corner and cry.

You'll be glad to know I didn't do either. Mark and I ate tuna with a soy and citrus sauce, egg noodles and stir-fried veg for dinner. And very lovely it was too.
