Fill a large pot about three-quarters full of water.
When it begins to boil, add a few cinnamon sticks - about
4 cinnamon sticks for every 20 medium size cones you plan
Let the cinnamon gently boil in the water
for 5 minutes, then add pine cones. They are done when each
petal is completely saturated. They will become a very dark
color, and their grain will show up. Lay cones on a wire
rack to dry completely.
