Preheat oven to 225 degrees.

Combine all ingredients except raisins in a very large bowl and mix until everything is well combined. You may need to slightly warm the syrup or honey if it is too sticky – it needs to be runny to coat everything.

Spread onto a cookie sheet and place in oven. Stir about every 10 to 15 minutes until everything is golden brown, usually about an hour. Keep an eye on it – don’t let it burn!

Remove from oven and add raisins or other dried fruit, if using. Let cool completely and store in airtight containers.
