I have a bunch of wild Blackberries, about 11 pounds, and i decided to make jam.

I looked up several recipes but i was kind of confused about the sterilization part.

The goal is to can the Jam and then boil it for 10 minutes and thats it? Theres no need to sterilize the jar previously right?

And, are the screw on lid jars good for canning jam? I saw a lot of recipes and all of them used Mason Jars, here in my country they are pretty much nonexistent, everyone uses the regular screw on lid jars.

Most people keep the jam in the refrigerator even when unopened. Im unsure if that changes anything. Im very new to this.
