I found one that is similar to the one I mentioned - here's the link so you can print it out for yourself.
This one is by Jasper White.
It is a somewhat long process (I haven't tried it myself yet), but if you can't get the buns in your area it is quicker than trying to have them shipped.
Although not mentioned in the recipe, I use a food processor to knead dough all the time and it works great.
I originally found this through a search at
http://www.ichef.com which then linked me to
If you go to ichef be for warned of a lot of pop ups.
