Sourdough discard works really similarly to buttermilk here, thanks to its acidity and lactic acid. It's perfect for making a tenderizing brine for fried chicken. If I have a lot of discard to use up, I'm making these chicken tenders! They're moist on the inside (thanks to the sourdough discard + pickle juice brine) and crispy and flavorful on the outside.
3-4poundsboneless, skinless chicken breast,cut into chicken tenders (from 4-5 breasts)
For the Coating
1 ½cupsall purpose flour
½cupcornstarch
1teaspoonbaking powder
2teaspoonskosher salt
For Frying
4cupsvegetable or peanut oil
Directions
Combine the seasoning ingredients in a medium bowl.In a large bowl, whisk together the starter, pickle juice, egg, and 2 tablespoons of the seasoning mix until smooth. Add in the chicken tenders and let brine at room temperature for 20-30 minutes, OR in the fridge for up to 8 hours, letting the chicken sit at room temperature for 20 minutes before proceeding to take the chill off. This will help with more even cooking.Heat 1 ½-2 inches of oil in a deep skillet or Dutch oven over medium heat. You're aiming for a temperature of 375 before the chicken goes in. In a large bowl, whisk together the flour, cornstarch, baking powder, 2 teaspoons salt, and the remaining seasoning mixture. Add ¼ cup of the chicken brine and work into the flour with your fingers. This will make clumps that will be so good when fried! Remove the chicken pieces from the brine one at a time and toss in the flour mixture to coat. Place off to the side of the bowl. Continue until all the chicken tenders have been coated. You'll want to keep them in the flour bowl at this stage.Grab one piece of chicken at a time with tongs, shake the as much flour off as you can, and gently lower into the hot oil. Be careful not to overcrowd. The oil temperature will drop, so adjust the heat as needed to maintain it above 325 degrees. Cook - undisturbed - for 2-3 minutes on the first side, until deeply golden brown. Flip the pieces carefully and cook on the second side about 1-2 minutes longer. Remove to a wire rack and sprinkle with additional salt. Continue until all pieces have been cooked. Serve immediately.
Notes
The discard - You want the discard that's on the older, liquidy side. It should be sour! The acid will work to tenderize the chicken here.If you want to use whole, bone-in chicken pieces, all the steps of this recipe will stay the same, you just may need to tweak the cook time slightly.
