Preheat oven to 300 degrees. Mix together oats, coconut, nuts, syrup, oil, sugar, sesame seeds, salt, and nutmeg. Spread granola in an even layer on a rimmed baking sheet. Bake, stirring every 10 minutes, for 40 minutes. Add raisins, and bake until granola is toasted, about 10 minutes more. Let cool completely.
