Hehe, depends on how critical you are. I would not set out to make a Rochefort 10 extract clone, but if I was going do do it, this is what I would do: Make a few kilograms of dark candi sugar (you will find tutorials on google. Search for "Making Candi Sugar". Get a proper digial candi-thermometer too), get some pale malt extract, get the same hops as in the recipe above.
Use a program like BeerSmith to work out how much extract, hops and home made candi sugar you need to get right gravity (circa 1.095) and aprox ABV 11.3% and the same IBU (International Bitterness Units) (circa IBU: 25 is my guess)
Get the right yeast: Belgian Abbey II (Wyeast #1762). Make 2 liter starter. Ferment relatively warm, maybe 75*F (my guess: pulled this number from the wyeast website).
If you wonder what words like "Starter" and which of the ingredients are hops, get the "How to brew"-book. It shows you how to do everything!
Be sure to wash your equipment before you start. Shouldn't be too bad
PS: after brewing, wait a year before you drink it.
