Oh.. I was wonder how to make raspberry jelly
and spent much time to find its recipe. If you're still interested here it is: First you will need to smash your berries and extract all the juice that you can from them. It is recommended to put the berries in a pan on low heat until berries are hot. Then pour them into the cloth-lined bowl, draw edges of cloth together and tie tightly with sturdy string.Tie a loop in the end of the string and hang this cloth bag on the hook under your cabinet, with the large liquid measuring cup under it. Be sure the bag is hanging high enough so it won’t dip into the juice in the measuring cup, and low enough so it doesn’t allow drops to spatter your walls.
The rest is in the article which I shared above.
