Very good point about the food and the smell too.
Do you have a health food store in the area? Vanilla Beans would work, also cinnamon sticks, Dried Basil, Apple Mint dried (lay flat outside in the sun and put in a canning jar. Open boxes of baking soda set in the cabinet. Also dried lavender. Open a jar of cloves. Dried lemon and lime peels. All of those can be dried outside on a cookie sheet in the sun or use a food dehydrator.
