  1. Was super-easy to make & came out amazing! Was a bit hesitant with some of the amounts in spices but stuck to them as instructions said & was glad I did. Would have taken a pic but it didn’t last long enough to so. This will definitely be one of my go-to recipes for the hubby & me.

      1. Still 5-star rating! I would like to know if this recipe can be doubled, as every time I have made this with the intention of freezing smaller portions it never lasts long enough to do so. (Some recipes cannot just be doubled so easy, and with the cost of groceries these days I would rather not find out the hard way on this).

        Thank you again!
