Can I make this without buttermilk?
Yes. Mix 1 cup milk with 1 tablespoon lemon juice or white vinegar. Let it sit 5 minutes, then use it in place of buttermilk. Whole milk is best, but any milk works. (It is not identical to cultured buttermilk, but it does the job.)
Should I use yellow or white cornmeal?
Either works. Yellow cornmeal tastes a little more corn-forward and looks more golden. Use fine or medium grind for the most tender texture.
Note: This recipe uses plain cornmeal, not self-rising.
Why rest the batter?
Cornmeal needs a few minutes to drink up the liquid. That short rest makes the crumb more tender and less gritty.
Can I bake it in a cast iron skillet?
Absolutely. A 9-inch skillet is closest to an 8x8 pan and gives you those crispy edges. A 10-inch skillet works too, but the cornbread will be thinner and will likely bake faster. If you go 10-inch, start checking around 16 to 18 minutes.
For extra crunch, preheat the skillet in the oven, then carefully add a little butter and swirl before you pour in the batter.
How do I keep sweet cornbread from turning out dry?
Do not overbake. Pull it when a toothpick comes out with a few moist crumbs. If you like a more exact cue, aim for an internal temperature of about 200 to 205°F in the center.
Also measure cornmeal and flour by spooning into the cup and leveling, not packing. (Even better, use a scale.)
Can I add corn kernels or jalapeños?
Yes. Stir in up to 3/4 cup drained corn (canned or thawed frozen). For heat, add 1 finely diced jalapeño. If you go spicy, I like keeping the honey in the batter for sweet-heat balance.
