Can frozen blackberries be used when making/canning blackberry jam at a later date.

Canned or frozen fruit or fruit juice can be used to make jellied products. If you use commercially canned or frozen products, select those that have no added sugar. It's best if canned fruits are canned in their own juice. Because commercial canned or frozen products are made from fully ripe fruit (which are lower in pectin than under-ripe fruit), pectin must be added.
