Storing bone broth in freezer?

What could be the alternatives to store bone broth in freezer?

I'm doing in glass jars, somehow ice takes too long to melt, hard for me to adapt the broth in lifestyle.

Prefer some utensil, where the shape of ice might easily fit in boiling pot so could quickly boil the broth after taking it out of freezer.

Something convenient, hygienic and reasonably priced.

Thanks for taking time to read. Tweet
