You will need:
-3-5 red roses
-one 100-gram chocolate bar (the better the chocolate, the better the chocolate-covered roses)
-a cooking pot
-a bowl (preferably glass) that is a bit too big to fit in to the cooking pot so that when it rests inside the pot there is at least 3 inches between the bottom of the bowl and that of the pot
-a glass (big enough to easily fit an entire rose flower inside)
Apparently the darker red the color of the roses, the more tasteful they are (be sure to avoid roses colored with artificial coloring added to their water, such as the blue and purple 'varieties' in stores). Organic is generally better, as for any other food, so that extra chemicals from pesticides/herbicides/artificial fertilizers can be avoided, and some flower shops will try to spray the flowers with a waxy spray to make them shinier after they've compiled your bouquet, so be sure to ask them not to before this happens.
