Nixtamalized Cornbread

Instructions

1. • 6½ cups water
 
   • 2¼ cups (14 ounces) dried field corn 
   • 3¼ teaspoons pickling lime

     
   In large saucepan, combine water and corn and bring to boil over high heat. Reduce heat to low and simmer until corn has softened slightly, about 10 minutes. Remove saucepan from heat and whisk in pickling lime until dissolved and corn turns yellow-orange, about 30 seconds. Cover and let sit at room temperature for at least 12 hours or up to 24 hours. 
   
2. • 16 tablespoons unsalted butter, cut into 8 equal pieces

   • 2 teaspoons vegetable oil

     
   Adjust oven rack to middle position and heat oven to 400 degrees F/200 degrees C. Heat 7 pieces butter in 12-inch cast-iron skillet over medium-high heat until it begins to turn golden, about 3 minutes. Continue to cook, swirling skillet constantly, until butter is dark golden brown and has nutty aroma, 1 to 3 minutes; transfer to medium bowl. Add remaining 1 piece butter to bowl of browned butter and stir until completely melted; set aside. Wipe skillet clean with paper towels. Add oil to skillet and transfer to oven.  
3. • 1¾ cups (12¼ ounces) sugar
 
   • 2 teaspoons baking powder
 
   • 1¼ teaspoons salt
 
   • 1¼ cups whole milk
 
   • 3 large eggs
 
   • 1 cup plus 7 tablespoons (7 ounces) all-purpose flour
   Whisk sugar, salt, and baking powder together in medium bowl and set aside. Drain corn in colander. Place colander in large bowl and fill with water. Massage corn in water for 30 seconds, then lift colander and discard water in bowl. Repeat massaging 2 times with fresh water. Transfer rinsed corn to food processor and process until coarsely ground, about 1 minute, scraping down sides of bowl as needed. Add milk and browned butter and process until combined, about 1 minute, scraping down sides of bowl as needed. Add eggs and process until combined, about 30 seconds. Add sugar mixture and process until combined, about 30 seconds. Transfer mixture to large bowl. Using rubber spatula, fold in flour until just combined and no clumps of flour remain, about 15 folds. 
4. Remove skillet from oven. Reduce heat to 350 degrees F/180 degrees C. Scrape batter into preheated skillet, smooth top with spatula, and bake until top is deep golden and toothpick inserted in center comes out clean, 60 to 70 minutes, rotating skillet halfway through baking. Use metal spatula to carefully slide cornbread onto wire rack set in rimmed baking sheet. Let cool for 30 minutes. Slice into wedges and serve.
