The smell of fruit mince pies baking takes me back to childhood and my mum's kitchen at Christmas when mince pies, Christmas cakes, gingerbread and all sorts of goodies were baked by her.
Also love the smell of cinnamon.
There again I also love to smell a curry cooking - when my son and his girlfriend visit I usually make a chicken curry for them and he always comments on the delicious smell wafting from the kitchen.
