Here's the extra brief version of the Kasteel bier recipe from Beer Captured.
heat 1 gallon of water @ 155 F
Add:
4 oz Munich
4 oz biscuit
2 oz aromatic
Steep for 30 minutes @ 150 F. Rinse with 1/2 gallon @ 150 F.
Bring to a boil then add:
9.5 lb extra light DME
2 lb clear candi sugar
8 oz invert sugar (lyle's golden syrup)
2 oz styrian goldings @ 4.5% (9 HBU)
Add water to make up 4 gallons. Boil for 45 minutes, then add:
1/2 oz styran goldings (flavor)
1/4 oz bitter orange peel
1 tsp Irish moss
Boil for 13 minutes, then add:
1/2 oz Saaz (aroma)
1/2 oz bitter orange peel
Boil 2 minutes, chill under 70 F, strain, and fill to make 5 1/8 gallons. OG = 1.102 - 1.103.
Recommended yeast is Wyeast 1214 Belgian abbey or Wyeast 1388 Belgian strong. Both should ferment at 70 - 72 F.
Primary for 7 days (or when done), then rack to secondary. Hit it with another dose of yeast 3 days before bottling.
Bottle when fermentation is done, FG is achieved (1.016-1.017), and beer has cleared (8 weeks or so). Prime with 1/2 cup corn sugar and 1/3 cup clear candi in 2 cups water. Let prime @ 70 F for 6 weeks, then store in cellar.

I stand by this book totally being worth the purchase. If nothing else it provides some good suggestions for a beer shopping list. We have made four excellent beers out of here (Fat Tire, Chimay Grande Reserve, Hacker-Pschorr Dunkel Weiss, and Shakemantle Ginger).
But, I mentioned that the recipes are not always perfectly clear. For this recipe, I noticed something odd. When you get your 1.5 gallons up to a boil, you add all the fermentables (and hops). When you add water (1+ gallons, I'm guessing) you will cool it off a lot. Should you continue to account time for the hops? I'd say no...but I'd just wait for the boil to re-start, then dump in the Styrians.
You could also re-adjust the recipe for a late DME addition and probably cut the hops in half. Plus, boiling a heavy wort like this will probably caramelize it somewhat...the flavor may be nice (although you could fix that with different specialty grains instead), but the beer will darken up. This is something that a little quality time with BeerSmith will fix right up.
