There are sites that have youtube on making Jams and jellies...it is listed in "eat the weeds" as edible..but it is all internet..i have not ..eaten them. (would like to have time to make jam..)
1 ½ qts. of Beautyberries, washed and clean of green stems and leaves. Cover with 2 qts. water.Boil 20 minutes and strain to make infusion. Use 3 cups of the infusion, bring to boil, add 1 envelope Sure-Jell and 4 ½ cups sugar. Bring to second boiland boil 2 minutes. Remove from heat and let stand until foam forms. Skim off foam, pour into sterilized jars, cap.
UPDATE: One of my students, Fred, does a lot of foraging and has lived his life in mosquito-ladened Florida. He reports: [Beautyberry’s] “jelly is awesome but I really love the beautyberry for its insect repellent properties. After learning about this from a Green Deane class and being an avid forager myself I decided to use the beautyberry as a bug repellent so it wouldn’t slow down my summer foraging (Florida summer mosquitoes can be horrible). I pretty much chopped up a plant(leaves and stems) and boiled it in a pot and let it cool and strained the brown liquid into my blender, about 1 1/2 cups. In a separate pot I warmed some organic neem oil (1 cup) with 1 ounce of beeswax until melted. Then you turn the blender on and pour in the oil mixture very slowly and it becomes a cream. I have to say hands down the best insect repellent ever! Because its a creme on july/august days one application is all you need for the entire day even when your sweating.”
