Buy Cinnamon Powder or Cinnamon Sticks for Freshness?

http://www.traditional-foods.com/profiles/cinnamon-powder/<br /><br />We normally recommend buying spices whole and grinding them at home for optimum freshness, but cinnamon sticks can be very hard to grind at home. This is a case where we recommend you purchase ground cinnamon if you need it ground in cooking and drinks.
