So I'm about to come into a lot—and I mean a lot—of duck fat, and I'm thinking maybe I could repackage it as Christmas gifts (you know, with a basket of potatoes or something, because I'm a class act). How would you do this? Portion it into little tins or other containers? It should be an airtight seal, right? Any ideas where to find appropriate containers? Could I use little half-pint canning jars? These should then be frozen, right? I just don't want 7 pounds of good fat to go to waste! Is this the right board for this topic?
