This is a real risotto, the kind you have to stir for half an hour, so don't attempt this recipe unless your arms are in good health or you've got some stirrer elves! Frozen broad beans are easy to find in Australia, impossible to find in Canada and I don't know about anywhere else. Obviously it's best if you can get fresh ones, otherwise use frozen ones, otherwise substitute frozen baby lima beans (don't worry about peeling these). As for bacon, I prefer back bacon, it is lean and crisps up very well, but you can use the streakier kind if you like. I have also tried this recipe using half reggiano, half aged cheddar because that's all I had in the fridge, and it tasted just as good as the original. I got this recipe on the web somewhere a couple of years ago but can't remember the details, nor can Google. Note that stirring time is included in prep time because it's anything but passive!
