Flowering Tea Turning Edible Dried Hibiscus Flowers Into Tea?

Turning edible dried hibiscus flowers into tea? - flowering tea

So I have to make hibiscus tea for the school ... But we found our way to the hibiscus flower is a fruit snack. There are thirty dried, candied flowers, but are not dry bones ... This leads me to believe that they are not stiff. What can I do to be able to tea? I have in the oven at low temperature to 200 degrees, and I let them pass. Is that correct?
