For me, the smell of home is fresh baked chocolate chip cookies. Yesterday I had this urge to make some, but didn't actually get up the energy to do it until just a while ago. Now the last batch is in the oven and I've got piles of cookies to enjoy. And the house smells like cookies. Yay!
I also used mom's big mixer to make them, which I have to say is just so much easier than using a hand mixer. When I get my own place again I am going to have to get one.
