Steps

Before you start

Preheat your oven to 400°F (200°C) and place a 10-inch (25 cm) cast-iron skillet inside to heat
Use active or recently fed sourdough discard at room temperature
Have all ingredients measured and ready before you begin

1
Mix dry ingredients
- In a medium mixing bowl, whisk together the all-purpose flour, cornmeal, baking powder, salt, and black pepper until combined and no lumps remain.
- Set aside.
+ Show details− Hide details
Ready when: mixture is uniform and light
Tip: Whisk the dry ingredients thoroughly to distribute the baking powder evenly, ensuring even rise throughout the bread.
2
Combine wet ingredients
- In a small bowl, whisk together the sourdough discard, buttermilk, egg, and honey until smooth and well incorporated.

Ready when: mixture is smooth with no visible lumps
Tip: Make sure the sourdough discard is well mixed so there are no pockets of concentrated starter.
3
Fold wet into dry
- Pour the wet ingredients into the dry ingredients and fold together using a rubber spatula until just combined.
- Do not overmix; a few flour streaks are fine.
- The batter will be thick and slightly lumpy.

Ready when: ingredients are just combined with no visible pockets of dry flour
Tip: Overmixing develops gluten and produces a tough, dense crumb. Stop folding as soon as you don't see dry streaks.
4
Fold in corn and cheese
- Gently fold in the corn kernels (patted dry to remove excess moisture), sharp cheddar, and diced jalapeño (if using).
- Mix until evenly distributed throughout the batter.
+ Show details− Hide details
Ready when: corn, cheese, and jalapeño are evenly distributed
Tip: Patting the corn dry prevents excess moisture in the batter, which can make the bread dense or wet.
5
Prepare hot skilletOven 400°F / 205°C
- Carefully remove the preheated 10-inch (25 cm) cast-iron skillet from the oven.
- Add the cold butter to the hot skillet and swirl to coat the bottom and sides evenly.
- The butter should sizzle and coat the pan within 10–15 seconds.
+ Show details− Hide details
Ready when: butter is melted and foamy, coating the skillet
Tip: Use an oven mitt to protect your hand when removing the hot skillet. Work quickly so the skillet stays hot when you add the batter.
6
Pour and bakeOven 400°F / 205°C
- Pour the batter into the hot buttered skillet, spreading it evenly with a spatula.
- Place immediately into the 400°F (200°C) oven.
- Bake for 28–32 minutes, until the top is golden brown and a toothpick inserted in the center comes out clean or with just a few crumbs (not wet batter).
+ Show details− Hide details
Ready when: top is golden brown, edges are slightly pulled away from the skillet, and a toothpick inserted in the center comes out clean
Tip: Do not open the oven door in the first 20 minutes, as sudden temperature drops can interfere with rise. The skillet will have a dark crust on the bottom; this is intentional and creates wonderful flavor.
7
Cool briefly
- Remove the skillet from the oven using an oven mitt.
- Let the bread rest in the skillet for 5 minutes, which allows the crumb to set and makes slicing easier.
+ Show details− Hide details
Ready when: bread has cooled enough to handle but is still warm
Tip: Cooling briefly in the skillet helps the bread hold together when sliced, since the sourdough structure is still tender.
8
Turn out and serve
- Run a thin knife around the edges of the bread to loosen it from the skillet.
- Using an oven mitt, carefully tip the skillet to release the bread onto a cutting board or wire rack.
- Serve warm, cut into wedges or slices, with butter if desired.
+ Show details− Hide details
Ready when: bread is released cleanly from the skillet
Tip: If the bread sticks, run the knife around the edges again and ease it out gently rather than forcing it, which can break the loaf.

Tips

This recipe is perfect for using sourdough starter discard—the tangy flavor complements the corn and cheddar beautifully without requiring a long fermentation.
For extra flavor, allow the batter to rest at room temperature for 20–30 minutes before pouring into the hot skillet; the sourdough will ferment slightly and add subtle depth.
A well-seasoned cast-iron skillet creates the best crust. If using a stainless steel or regular baking pan, reduce baking time by 2–3 minutes and monitor the bottom to prevent excessive browning.
Serve this bread warm alongside chili, vegetable soup, or pulled pork for a hearty meal. Leftover slices are excellent split and toasted with butter for breakfast.

Make ahead

Prepare the dry ingredients (step 1) up to 1 day ahead and store in an airtight container. Mix the wet ingredients no more than 15 minutes before folding to prevent over-fermentation from the sourdough starter.

Storage & reheating

Room temperature (covered, up to 2 days). Refrigerate (in an airtight container, up to 4 days); reheat wrapped in foil at 350°F (175°C) for 10 minutes. Freeze (wrap tightly in plastic wrap and foil, up to 3 months); thaw at room temperature and reheat as above.

Substitutions

buttermilk → regular milk mixed with 1 tablespoon fresh lemon juice or white vinegar, left to sit for 5 minutes. This creates a makeshift buttermilk with similar acidity and tenderness.
corn kernels, fresh or frozen (thawed) → 1 cup (150 g) corn kernels replaced with 1 cup (140 g) diced red or yellow bell pepper plus 0.5 cup (75 g) corn, or omitted entirely for a plain version. Bell pepper adds moisture and sweetness while maintaining the savory veggie element.
sharp cheddar cheese, shredded → Gruyère, aged Gouda, or sharp white cheddar in equal amounts. Any aged, flavorful hard cheese will add depth; avoid mild or very young cheeses, which lack character.
fresh jalapeño pepper → 1 tablespoon hot sauce (Frank's RedHot or similar) whisked into the wet ingredients, or omit for no heat. Hot sauce adds flavor without chunks; this is ideal if you prefer a smoother crumb or don't have fresh jalapeños on hand.
