Heat oven to 400˚F. Halve the tomatoes and place in a roasting pan or sheet tray. Roast for 18 to 20 minutes, until the tomatoes have softened and are starting to brown. Remove from oven and toss roasted tomatoes with za’atar.: As the oven warms, you will notice a dry, warming air that sets the stage for caramelization, which helps the cherry tomatoes blister and sweeten; if the oven is cooler than indicated, the tomatoes will steam rather than roast, losing that concentrated sweetness, so always preheat fully.
Place an 8” cast iron skillet, with 2 teaspoons butter, in the oven until the butter has melted. In a bowl, combine the flour with the cornmeal, baking powder, and salt. In a separate bowl, whisk together egg, honey, melted butter, and milk. Pour into the dry ingredients and stir until just combined. Fold in the corn.: The smell of tomato juice hitting a hot pan is bright and slightly sharp, and as the tomatoes sit cut side up they begin to concentrate their juices; crowding the pan can prevent browning, so spread them in a single layer for best results.
Remove the skillet from the oven and swirl the butter around the skillet. Pour the cornbread mix into the pan and return to oven. Bake for 15 minutes or until set and golden.: When the skins wrinkle and a few edges caramelize, you will get a rich, almost jammy aroma that signals readiness; if you remove them too early they will remain acidic and underripe in flavor, so look for gentle browning as your cue.
Take the cornbread and cut it into wedges. Top with tomato mixture and sprinkle with parsley and olive oil before serving.: The heated oils and sugars in the tomatoes bloom the za’atar , releasing sesame and herb notes into the mix; tossing while hot allows the spice to coat evenly, but avoid overdressing or the mixture may become soggy.
Place an 8” cast iron skillet, with 2 teaspoons butter, in the oven until the butter has melted: You will hear a soft sizzle as the butter hits the hot skillet, and a nutty aroma will develop which gives the cornbread a toasty base; skipping this step can lead to a paler, less flavorful crust so preheating the skillet is worth the small effort.
In a bowl, combine the flour with the cornmeal, baking powder, and salt: Dry ingredients mixed thoroughly give even lift and texture; when these are well combined the cornbread bakes with a uniform crumb, but uneven mixing can create pockets of leavening or dense spots.
In a separate bowl, whisk together egg, honey, melted butter, and milk: The liquids should look cohesive and glossy when properly whisked, which helps the batter bind without overmixing; if the butter is too hot it can cook the egg, so ensure it is just warm before combining.
Pour into the dry ingredients and stir until just combined: You will see a slightly lumpy batter that holds together, not completely smooth, which is desirable for tender cornbread; overworking the batter activates gluten and produces a tough crumb, so stop mixing once moistened.
Fold in the corn: Folding preserves air and distributes the corn kernels evenly without deflating the batter; the kernels should glint through the mix, promising pops of sweetness; avoid beating them in aggressively or the batter will lose lift.
Remove the skillet from the oven and swirl the butter around the skillet: As the hot skillet meets the butter, a fragrant, toasty note develops and the base sizzles slightly, creating a protective, crisp layer; be careful handling the skillet and use an oven mitt because it will be extremely hot.
Pour the cornbread mix into the pan and return to oven: The batter should sizzle faintly as it hits the hot butter, which helps form a golden crust; if the batter does not sizzle the skillet may not have been hot enough, leaving a paler edge.
Bake for 15 minutes or until set and golden: Look for a golden top and a springy center; a toothpick inserted in the middle should come out with a few moist crumbs but not wet batter, and the aroma will be warm and toasty; underbaking yields a gummy texture so ensure the center is set.
Take the cornbread and cut it into wedges: The bread will smell buttery and slightly sweet, and cutting into wedges reveals a tender crumb with flecks of cornmeal ; let it rest briefly if the center is very hot to avoid crumbling.
Top with tomato mixture and sprinkle with parsley and olive oil before serving: The final assembly delivers contrasting temperatures and textures, the warm roasted tomatoes soften the cornbread slightly while the olive oil and parsley add freshness and a silky finish; add the tomatoes while still warm for the best melding of flavors, but avoid saturating the bread so it keeps some structure.
