Chives are the anemic kid brother of the green onion. Available in both powder and stick form. Cinnamon sticks are cool to have around, although odds are you won't use them very often. You should already have bought a jar of the powdered variety. Cloves are very strong in flavor, so they should be used sparingly.
Cloves make an interesting addition to a variety of dishes.
It is a unique flavor, but is not a spice which you will want to buy until you have a recipe which calls for it. Cumin is a very useful spice. Sold both as seeds and a powder. Don't be put off by the fact that it has a fragrance reminiscent of human body odor. Curry can be any one of a variety of spice mixtures.
