Smell...
KAREN BARNES, EDITOR
That’s often the first thing that entices you to eat something, isn’t it? It’s the best welcome when you walk into someone’s house and your nostrils are teased with the aroma of a casserole cooking in wine, or the warm yeasty smell of baking bread emanating from the kitchen. It sells houses; it encourages people to abandon their shopping list and detour to the bakery counter at the supermarket; it can win you friends.
