While homemade cornbread has a crisp surface and a moist center, store-bought mixes like Jiffy often maintain a crumbly feel throughout. Thankfully, a bit of mayo can help.
Mayo can make your Jiffy cornbread fluffier and enhance its taste with a touch of tangy flavor. The emulsion also binds the batter together, lending it a more cohesive structure.
Use a 1/2 cup of mayo for every box of corn muffin mix. All you have to do is beat the eggs and mayo together until they're well combined and then add the milk and muffin mix.
