Normally I don't think it's a good idea to perfume a room while people are eating because it interferes with the pleasure of eating. For example, we went to a steakhouse once and I was so looking forward to my steak and baked potato. But my husband ordered a baked sweet potato and sprinkled cinnamon on it which was so unpleasant to smell while I was trying to enjoy my steak and don't get me wrong, I love cinnamon more than anyone but not while eating steak.
Anyway, the good news is that dessert is different and I wouldn't mind smelling cinnamon while I enjoy a slice of cheesecake. One of my favorite things to do in my house, and I do it often, is to place fruits and spices in a little saucepan with water. I put orange rinds, cinnamon stick and cloves in a saucepan with a little water and heat it gently on the stovetop. It makes the whole living area smell delightfully festive and top up the water when it dwindles down. it doesn't have to boil, just simmer at the lowest setting. And make sure you have plenty of coffee brewing, I can't imagine a better smell than that.
