Check with other recipes, it may have been a misprint. I have only found 6 oz boxes with 2 pouches of 3 oz. If it is not a misprint, you 6 plus 2/3 of another pouch.

I would just use the 6 oz. package. I find that liquid pectin can result in a stiff set and I doubt you'll discover there's much difference one way or the other with a smaller amount.

Just my personal experience. Your mileage may vary.

Thank you! I'll use the 6 oz and just roll with it.
