I made this granola as the recipe stated, only I used a mixture of whole almonds and chopped pecans instead of pepitas. I also used sliced almonds instead of chopped and I cut the recipe in half. The recipe turned out fairly well. The granola is well balanced with the nuts and oats. I think it could have used a bit more of each of the flavoring ingredients (honey, syrup, vanilla, cinnamon) to give it a bit more flavor since it mostly just tastes like roasted nuts (which isn't such a bad thing). Also, my granola only cooked for about 35-40 minutes and it probably should have been stirred more often than every 15 minutes. I do not suggest substituting with pecans, unless you add them in after the rest of the granola has started baking because they burn more easily than the other components.
All in all the granola was pretty good, but I will adjust the baking time, number of times I stir it, and the amount of flavoring ingredients next time to make it great.
