High-speed hamburger

edited on 27/08/12: I'm upgrading this to three stars as I decided to give this recipe another go in desperation for a quick, easy burger recipe that seemed relatively low in fat. This time I put the burgers in the fridge to firm up for about a half an hour before grilling them on my griddle pan. They still came out a bit soft for my liking, but the flavour was really good and my husband said he liked them and wouldn't mind having them again. So, for a quick burger recipe, it's not too bad. I served these on wholemeal rolls with cheese slices.

I was happy to see a burger recipe in a Nigella book as I normally don't have very good results when trying to make my own. Unfortunately, this recipe didn't really help me as, as usual for me, they came out a bit mushier than I was hoping for and the mixture was a bit too wet for my tastes. I didn't use a burger press as per Nigella's suggestion (I don't have one!), so maybe that's part of the problem.
