It's an excellent recipe for using up some fruit that might be looking past its best a little. I actually had some plums to use up, but I should think it would work just as well with something like apricots, and even apples.
The sugary syrup is poured one when they come out of the oven and then left to set, hence the 'crunch' part of the title. Of course, you could leave this bit out if you wanted to cut back on the sugar content.
The only downside with this cake is that it's not so great for transporting - probably not the best for lunchboxes (although hubby did manage it just fine. I can't say if all of the bits stayed on but they certainly got eaten, detached or not.)
Any other fruit you could think of that would be good for this recipe?
