Here's about as basic as you can get:
8-10 cups "Stuff" total (oasts, wheat germ, founrd flax, dried fruits, coconut, nuts...whatever you want)
1-2 cups liquid (if you use honey, molasses, syrups include that in this measure) (1/4-1/2 fat, i.e., oil)
dry sweetener, vanilla, and/or spices to taste
Mix all together till dry ingredients are thouroughly coated. Spread on baking trays - this quantity should take at least two. Bake at ~300F for an hour or so, stirring every 10-20 minutes and watching carefully for burning/overbrowning.
If you're someone who does better with a 'real recipe' here goes:
~9 c. oats (sub whatever granola ingredients you like to total 9 c.)
1/2 c. water
1/2 c. oil of choice
1/3 c. honey
spice to taste (cinnamon, nutmeg, cardamom are suggestions)
Bake as above.
Hope this helps!
Note: You want your oats/other ingredients thoroughly moist, but not 'wet' or sticking together too much, if that makes sense.
ETA: D'oh! Add raisins or other dried fruit AFTER baking!
