I found a recipe using a general search in yahoo.com.
Here it is:
Ingredients 2 cups of rose petals
2 1/2 cups of water
3 1/2 cups of sugar
1 lemon (or 1/4 cup lemon juice)
1 teaspoon vanilla extract
1 package of pectin
Preparation Take your roses and snip off the white part at the bottom of the petals.
You can just grasp the rose from the top and snip the bottom. No need
to do it petal by petal.
Wash them thoroughly.
Place in a pot ( I like using a glass pot for this) along with the water, the sugar,
the lemon juice, and the vanilla extract.
Bring to a boil, then reduce heat and let simmer for about 35 minutes.
Take the pectin and dissolve into about 1/2 a cup pf water and mix thoroughly.
Take dissolved pectin and pour in the simmering mixture stirring briskly.
Remove from heat. Let cool. Then put in jars. Can be kept in the fridge.
If you prefer you can put the water, rose petals and sugar in a blender or food processor before cooking. This way you don't have whole petals in your jam when it's done. The petals if not put through the blender can be nice and add texture so it's not necessary.
Enjoy!
