Method
Brine
- Combine the onion, salt, sugar, mustard seeds, peppercorns, bay leaves, and 1 cup (250 mL) water in a small saucepan. Bring to a boil over medium heat, stirring to dissolve the salt and sugar. Pour into a large bowl and let cool. Add the remaining 4 cups (1 L) of water and refrigerate until fully chilled.
- Add the chicken thighs to the cold brine in a non-reactive bowl, pressing to fully submerge, or place them in an extra-large resealable plastic bag set in a container. Cover or seal and refrigerate for at least 12 hours and up to 24 hours.
Buttermilk Marinade
- Drain and discard the brine. Rinse the thighs and pat dry thoroughly with paper towels.
- Combine buttermilk, paprika, celery seeds, and hot pepper sauce in a clean, large non-reactive bowl or container. Add the chicken and turn to coat well. Cover and refrigerate for at least 8 hours, up to 24 hours.
Coating and Frying
- Whisk together the flour, cornstarch, paprika, thyme, salt, garlic powder (if using), pepper, and cayenne. You may need extra flour mixture; any leftover coating can be used for frying vegetables.
- Scoop the beef tallow into a deep fryer, or pour the peanut oil into the fryer, and heat over medium heat to 350°F (180°C).
- Preheat the oven to 325°F (160°C).
- If making potato wedges, fry them first for 3½ minutes, until lightly browned but not cooked through. Transfer to the oven and bake for 30 minutes.
- Spoon 2 Tbsp (30 mL) of the buttermilk marinade into the flour mixture, whisking until small clumps form. Working with 1–2 pieces at a time, remove the chicken from the marinade and dredge in the flour mixture, turning and pressing to coat well. Place the coated pieces on a wire rack set over a baking sheet. Repeat until all pieces are coated.
- Carefully add the chicken thighs to the hot tallow, two at a time. Fry for 2½–3 minutes, until browned, then flip, cover, and fry for another 4½–5 minutes, or until deep golden-brown and crispy.
- Using tongs, transfer the chicken to a wire rack set over a baking sheet and place in the oven to keep warm.
- Repeat with the remaining chicken pieces. Fry the final batch for about 2 minutes longer and finish in the oven if necessary.
- Fry your blooming onion, if making.
- The internal temperature of the chicken thighs should reach 165°F (74°C). If needed, bake on the rack for an additional 5–10 minutes, then recheck the temperature.
Notes
- If time permits, brine the chicken for the full 24 hours for maximum juiciness.
- Use plain, unflavoured buttermilk only.
- Reheat leftover chicken thighs in an air fryer for the best results.
- If you don’t own a deep fryer, use the shallow fry method outlined in the original recipe.
