Sourdough starter discard gives this cornbread the most delicious sourdough tang! It's sweet (but not too sweet!), tender and moist, with that classic cornbread crumble. It's the perfect easy bread to go with all of your soups, chilis, and roasts this season!
Preheat oven to 325 degrees. Grease a 9 x 13-inch baking dish. In a large bowl, whisk together the butter, discard, sour cream, honey, and eggs until smooth. Stir in the JIFFY and salt until well combined. Transfer to the prepared baking dish. Bake for 40-45 minutes, until the edges are beginning to brown and a fork inserted into the center of the cornbread comes out clean. Cool at least 10 minutes before slicing.Store leftovers in an airtight container at room temperature for up to 5 days.
