Pour the warm water into a large bowl. It should be warm enough to activate the yeast but not hot enough to kill it.
Add the rapid rise yeast and honey. Stir and let sit at least 5 minutes, until foamy and bubbly.
Add the bread flour using the dip, level, and pour method so you don't pack in too much.
Add the kosher salt.
Stir by hand just until the flour is incorporated. Do not over mix — a few turns of the spoon is enough.
Optional: drizzle 1 to 2 teaspoons of oil over the dough and work it around by hand so it releases easily from the bowl later.
Cover the bowl and refrigerate at least 2 hours, or until the next day.
Grease a cast iron skillet well on the bottom and sides with shortening, oil, or bacon grease.
Turn the dough out onto a lightly floured surface. Knead with quarter turns, working in flour until the stickiness is gone — about 10 to 12 turns.
Shape the dough into a round and place it in the center of the greased skillet.
Optional: score the top with a few crisscross slits using a razor blade or sharp knife.
Let the bread rest in the pan for 30 minutes. Halfway through, preheat the oven to 425°F.
Bake for 30 minutes, checking a few minutes early if your oven runs hot.
Optional: brush the top lightly with butter for a slightly softer crust. Skip for extra crispness.
Cool slightly, lift from the pan, and slice while still warm.
