Delight the sense of smell from the moment people walk in the door. Plan to have bread baking in the oven, coffee brewing or meat roasting as they are arriving. Open the kitchen door to allow guests to follow the aroma and wander into the kitchen. Other ideas for delicious aromas include oranges and cinnamon simmering on the range, onions and garlic gently cooking in olive oil, fully ripe fruit in decorations, or rich chocolate cakes sliced at room temperature. Use extreme care with scents other than food.
Flowers are delightful, but too many flowers can make a room smell like a funeral parlor.
Choose unscented candles and flowers in areas where food is served. Consider possible allergies of guests and avoid overpowering room fresheners and incense.
