Homemade Granola

Granola is expensive for what it is.  My mom and sister-in-law both gave it out as gifts this Christmas.  So I decided to make my own, I must say I am a good cook.  I can follow recipes and if I don't things more often than not turn out fine.  My granola did not turn out okay.  It tastes a little like the burnt insides of an oven.  I used a recipe from Sharing the Table at Garland's Lodge (it was not the cookbook's fault), maybe it was the peanut butter mixture was cooked too long, maybe it was using a new oven, maybe granola is not my thing.  I will try granola again, I will try to get it right.  Now what can I do with 10 cups of slightly burnt tasting granola?
