Jiffy mix makes a fair cornbread. It’s not quite as lofty as homemade, you can’t tailor the sweetness, and it does contain partially hydrogenated lard. But the bread tastes fine and it’s marginally cheaper and quicker than homemade.
With that said, I’ve been baking my husband’s grandmother’s cornbread recipe for 15 years, and I think of her every time I do it. She was lovely, with a cloud of white hair and the gift of making everyone feel appreciated, from the smallest child to the most shy and awkward adult. She called recipes “rules” and she wrote out this rule for “Aunt Sally’s cornbread” for me in her own hand.
Whoever Aunt Sally was, she was definitely a Yankee. This cornbread is sweet.
Make it or buy it? Make it.
