I don't care much for oranges, but I love the smell of orange zest. It adds so much flavor to recipes, so it's annoying when you come across a recipe using it when oranges aren't in season. Which is why I started grated oranges when we have them and freezing the zest! That's three or four oranges worth of zest in the bowl. I'm sure it's way more than I'll need, but it stays fresh. It can also be substituted for lemon zest in most recipes, and I never have lemons. So it'll be used. Or I could just defrost it and smell it.
