Thirding the cinnamon ornaments. I’ve made them a couple of times. They make nice gifts (or decorations for your own tree) and they smell great.
That’s an idea… and I was thinking about making some of that cinnamon cocktail syrup I’ve read about for tiki drinks too.
That was basically my first thought - cinnamon vodka or cinnamon liqueur. I’ve got some chocolate rum infusing right now for chocolate peppermint martinis and I can think of a bunch of holiday drinks that would be more festive with cinnamon flavored booze plus you can’t make too much especially if you don’t add sugar to the spirit since it can’t spoil.
I’d agree with that statement, as qualified by “some spices” instead, and Cinnamon is one of the longer lasting ones. At least, it won’t turn to sawdust or take on spoiled flavors.
Sprinkle it on oatmeal with brown sugar. Some cut-up apple would make it even better.
Come to think of it, make apple crisp.
Howzabout sweet potatoes, too?
- Take a bite out of a raw apple (I like sweet ones).
- Sprinkle cinnamon on the exposed apple flesh.
- Take a bite out of that part.
- If you haven’t eaten the whole apple yet, go to step 2.
If you’ve also got some stale bread lying about, make a bread-custard pudding.
Cut up bread into a casserole dish. Beat eggs and milk together with sugar and/or honey and a dash of vanilla. Add copious amounts of cinnamon.
Bake.
Eat.
A yummy, lazy dessert.
Make some Ras el hanout and cook North African
Whenever I make French toast, I always whisk a little cinnamon, nutmeg, and brown sugar into the egg dip. A dash of cloves is nice too.
^ This.
I purchase spices in bulk from Penzeys, which points out that many/most spices are harvested but once a year so the notion that you need to re-purchase after six months is nonsensical, because the “new” stuff you’re buying might be six months old itself. The site Still Tasty gives a storage life of 3-4 years for cinnamon in a cool, dark place and does not recommend freezing.
Over time, the cinnamon will become less potent, but for most applications it will still be fine after a couple or even several years.
I like to mix it into vanilla yogurt before I eat it. My mom does, too. We came to this conclusion independently of each other, so there’s probably some merit to it outside of my being weird. And the yogurt can take a -lot- of cinnamon, so it’s a good way to quickly use it.
A favorite breakfast:
Rustic whole wheat bread, toasted, spread with peanut butter, drizzled with honey, and then liberally sprinkled with cinnamon. Slice bananas on top of it, too, if you like.
I second this idea! 
Can’t cinnamon be used in the garden to keep pests away?
…I googled it. Yes for ants, and other stuff.
