The actual cake mixture is more like a batter. It is quite runny so I decided to use a tinfoil tray instead of a spring-loaded cake tin as I didn't want any leaks.
As my oven in a fan oven, I reduced the temperature to 160 degrees C instead of 180 degrees C, and cooked it for 5 minutes longer. You really need to watch the cake after 40minutes as it can catch on top because of the amount of syrup and sugar in the cake. I had to cover mine with tinfoil.
Result - well, the top of the cake cracked a little and I need to play around with the temperature and cooking time for my oven for the next cake as the centre was still a little moist. It wasn't gingery enough for me, so I made a ginger and lemon fudge icing for the top and sprinkled over some chopped stem ginger.
Needs another attempt and a bit of tweaking, but it is very easy to do.
