Blackberry, Black Raspberry...
Add just enough water to cover your berries in a pot, then boil them for quite a while, cooking most of the juice out of the berries. Then strain all the chunks, pieces, skins and seeds out of the juice after cooking it down (can use cheesecloth or a fine strainer). BTW, you don't have to wash the berries super good before hand, with the straining method.
It takes 4 1/2 cups of the berry juice,
6 cups of sugar,
and one box of SURE-JELL Premium Fruit Pectin.
Bring the 4 1/2 cups of juice, and the box of Sure-Jell to a rapid boil.
Then add the 6 cups of sugar to it, and bring back to RAPID boil on HIGH heat for 1 solid minute (from the time it starts boiling again).
Immediately dip/pour the cooked jelly into your jars!
Then boil your jars of jelly submerged in water for 5 mins.......... remove from boiling water, retighten lids, and let stand for 24hrs.
VERY SIMPLE to make................... believe me, you'll thank yourself!
