Successfully avoiding a trip to the grocery again

You know the scenario: You're pressed for time to get that dish done by dinnertime or in time to leave with it for someone else's house and you realize you don't have as much of one ingredient as you thought you had. The recipe won't turn out the way you have come to expect. You're not sure whether you can fudge it with using less, but you have to try anyway because you've already started mixing the other parts.

This recipe is about embracing the unexpected and foisting it off on your friends at a potluck, which I did. And about avoiding a trip to the grocery for which there is no time, which I also did and made it to that potluck on time. And it's about finding another tasty use for backyard rosemary and other gardeners' summer tomatoes that show up unannounced at our place or appear in our Henry's Farm CSA box.

Running-Out-of-Cornmeal Cornbread (with bell and whistles)
alterations to Cook's Illustrated "All Purpose Cornbread" recipe
at least 6 servings

5 ounces unbleached all-purpose flour
4 ounces whole-wheat flour
3 ounces cornmeal
2 tsp baking powder
1/4 tsp baking soda
3/4 tsp table salt
1/4 cup packed light brown sugar
3 1/2 ounces fresh cooked corn kernels (or thawed frozen corn)
1 cup unsweetened kefir (or buttermilk)
2 large eggs
8 Tbsp unsalted butter, melted and cooled slightly
large pinch dried rosemary, crushed (this is the bell from my backyard plant)
one to two ripe garden tomatoes (this is a whistle)
a pinch of kosher salt or sea salt (this is a whistle)

Heat oven to 400 degrees Fahrenheit. Spray 8x8-inch glass baking dish with nonstick cooking spray. Whisk flours, cornmeal, baking powder, baking soda, salt in a bowl until combined and set aside.

In food processor or blender, process sugar, corn, kefir and eggs until combined. 

Make a well in the center of dry ingredients and pour in wet mixture. Fold together for a few turns of the spatula/spoon. Add melted butter and rosemary and fold until dry ingredients are just moistened.

Pour batter into baking dish. Smooth the top. Slice the tomatoes thinly and lay the slices on top of the batter so they just touch each other. Sprinkle with kosher/sea salt.

Bake about 25 to 35 minutes until golden brown and a toothpick inserted it the center comes out clean. Tomato slices will look as if they have sunken into the top. Take directly from oven to potluck and serve cornbread still warm out of the baking dish.
