Instructions

1. 1

   Brine the chicken

   Stir together the kefir, hot sauce, 1 tablespoon of kosher salt and 1 teaspoon of black pepper. Add the chicken and marinate for at least 1 hour; overnight is preferred.

2. 2

   Mix the dredge

   Combine the dry spices in a small bowl. In a shallow bowl, mix the flour and cornflour with three-quarters of the spice mixture; set the remaining spices aside.

3. 3

   Make the egg wash

   In a separate shallow dish, mix the water, vodka and one egg. Stir in ¼ cup of the seasoned flour mixture to make a smooth slurry.

4. 4

   Heat the fryer

   Preheat a deep fryer and bring the oil to 185–190°C (365–375°F). While it heats, take the chicken out of the marinade and let it come towards room temperature.

5. 5

   Coat and fry

   Let excess marinade drip off the chicken, or rinse it away with water. Dip each piece in the egg wash, then dredge it in the seasoned flour mixture. Fry the chicken for 4–6 minutes, depending on the thickness of the breasts. Transfer it to a cooling rack so excess oil can drain; alternatively, collect the oil on paper towels in a bowl.

6. 6

   Assemble sandwiches

   Toast the buns. Mix mayonnaise with your favourite hot sauce, then assemble the sandwiches with the fried chicken.

What is a Southern fried chicken sandwich?

Fried chicken is a well-established part of Southern American cooking, and this sandwich brings its seasoned, crunchy coating to a bun. The chicken gets a tangy kefir-and-hot-sauce marinade before it is dipped and dredged.

The method combines plain flour with cornflour and a spiced mix, giving the coating its crisp, savoury character. A hot-sauce mayonnaise adds a creamy, sharp contrast.

Nutrition and macros by portion

The nutrition label shows one serving as written: 822 calories, 36g protein, 118g carbs, 13g fat.

The bun, flour and cornflour provide most of the carbohydrates, while the chicken is the main source of protein. Frying oil and the mayonnaise used for serving contribute fat; add a vegetable side such as slaw or salad to round out the plate.

Why use kefir for the marinade?

Kefir provides a tangy base that clings to the chicken, while hot sauce seasons the brine with heat. The recipe calls for at least an hour of marinating, with overnight preferred, so allow for that time beyond the stated 25-minute cook time.

Building the seasoned coating

Spices: smoked paprika, pepper, cayenne, thyme, ginger, garlic, nutmeg and mustard make up the seasoning, with sage and vinegar powder listed as optional. Mix these first so they are distributed evenly.

Flour mix: combine the plain flour and cornflour with three-quarters of the spice mix. Keep the remaining quarter separate, as directed, and use ¼ cup of the seasoned flour to thicken the egg wash.

Getting an even crust

Dip each chicken piece in the egg wash before coating it in the seasoned flour. Let excess marinade drip away first so it does not make the flour mixture overly wet.

Work with one piece at a time, as the method specifies. A well-covered piece should have flour coating its surface before it goes into the fryer.

Frying and checking doneness

Oil temperature: heat the fryer to 185–190°C (365–375°F) before adding the chicken. The recipe gives a frying time of 4–6 minutes, with thicker breasts taking longer.

After frying: lift the chicken onto a cooling rack to drain excess oil. Check that the thickest part is cooked through before serving.

Putting the sandwich together

Toast the buns while the chicken drains, then mix mayonnaise with your favourite hot sauce. The recipe does not specify amounts for either, so adjust the mix to suit your taste.

Serve the chicken in the toasted buns with the spicy mayonnaise. A crisp salad or a simple slaw makes a fresh side alongside the crunchy coating.

Recipe notes & tips

• Marinate the chicken overnight if you want to follow the recipe’s preferred timing.
• Measure the oil temperature with a thermometer before frying.
• Mix the dry spices thoroughly before dividing them between the flour and the reserved portion.
• Let each piece drain on a rack after frying to keep its underside from sitting in oil.
• Toast the buns shortly before serving so they are warm when the chicken is ready.

Variations

• Adjust the heat: use more or less hot sauce in the mayonnaise to suit your preference.
• Skip optional spices: leave out the ground sage or vinegar powder if you do not have them.
• Add a crunchy side: serve with a crisp salad or slaw for fresh contrast.
• Change the bun: use another soft sandwich roll if you do not have sandwich buns.
• Make it less spicy: reduce the cayenne in the dredge and use a mild hot sauce.

Common mistakes to avoid

• Cold oil: wait until the fryer reaches 185–190°C before adding the chicken.
• Skipping the marinade: give the chicken at least 1 hour in the kefir mixture.
• Uneven coating: dip each piece in the egg wash before dredging it in the flour mix.
• Guessing the fry time: the recipe allows 4–6 minutes depending on breast thickness; check the thickest part is cooked through.
• Draining on a flat surface: use the cooling rack so excess oil can drip away.

How to store

Refrigerate leftover cooked chicken in a covered container and use within 3 days. Reheat in an oven until hot throughout to help restore some crispness; assemble with fresh buns and mayonnaise just before serving.
