Another odd one that is done out here is prickly pear cactus jelly. It is made with the flower buds? of prickly pear cactus plants.
Its pretty darn good too, again, something I havent made in years!!
Here is a good website for it.

Here are two recipes I found for cactus jelly
and this one website describes the "flower bud" I am talking about as a pear or called FRUIT; the cactus "leaves: are called PADS so the second recipe would actually be for the Pads I believe.
Prickly Pear Jelly
This recipe may sometimes be sticky depending on the maturity of the cactus.
4 cups cactus juice
1/2 cup lemon juice
1 1/2 pkg. powdered pectin
6 cups sugar
1/8 teaspoon salt
Use kitchen tongs to gather cactus fruit. Select ripe fruits and a few green fruits. Wash fruits with hand spray, place in large pan with water to almost cover. Cook for 10 minutes. Mash with potato masher and cook 10 minutes longer. Strain through cloth as for any other juice for jelly (see page 1).
Place cactus juice, lemon juice and pectin in large pan. Bring to boil, stirring constantly, and add sugar and salt all at once. Bring to a boil 3 minutes until gel stage is reached. Pour into sterile jars, leaving 1/8" headspace. Wipe jar rims, adjust lids and rings. Water bath 5 minutes.
Cactus Jelly
Remove spines from prickly pear cactus fruit, wash, cut in quarters, and put in pan, adding enough water to nearly cover. Cook slowly until fruit is very soft and almost a pulp. Strain through jelly bag moistened first with hot water. Let drain overnight or 12 hours (see page 1).
Heat juice quickly to a boil and boil for 5 minutes. Remove foam and measure liquid. Add 3/4 to 1 cup sugar for each cup of juice, and 1 tablespoon lemon or orange juice. Cook until gel stage is reached. Pour into sterile jars, leaving 1/8" headspace. Wipe jar rims, adjust lids and rings. Water bath 5 minutes.
