Expensive Chicken Sandwich

Ingredients

• 2 pieces Boneless Skinless Chicken Thighs (about 8 oz each, pounded to even thickness)
• 1 cup Buttermilk (for brining the chicken)
• 1 tablespoon Hot Sauce (adds a subtle kick to the brine)
• 1 cup All-Purpose Flour (for dredging the chicken)
• 1 teaspoon Salt (seasoning for brine and flour)
• 0.5 teaspoon Black Pepper (freshly ground)
• 4 cups Vegetable Oil (for deep‑frying, high smoke point oil)
• 2 pieces Brioche Buns (soft, slightly sweet buns)
• 2 leaves Romaine Lettuce (washed and dried)
• 2 slices Tomato (ripe, sliced about ¼ inch thick)
• 4 slices Pickles (dill, thinly sliced)
• 1 large Yellow Onion (thinly sliced for caramelization)
• 2 tablespoons Unsalted Butter (for caramelizing onions)
• 1 teaspoon Granulated Sugar (helps onions brown evenly)
• 1 tablespoon Caviar (high‑quality sturgeon caviar, rinsed and patted dry)
• 2 tablespoons Mayonnaise (base for the caviar sauce)
• 1 teaspoon Lemon Juice (brightens the caviar sauce)
• 1 teaspoon Dijon Mustard (adds tang to the sauce)
• 1 tablespoon Fresh Chives (finely chopped, folded into sauce)

Instructions

1. Brine the Chicken

   In a large mixing bowl combine buttermilk, hot sauce, ½ teaspoon salt, and ¼ teaspoon black pepper. Submerge the chicken thighs, turn to coat, and refrigerate for at least 30 minutes (up to 2 hours) to tenderize and flavor.

   Time: PT30M

   Temperature: 4°C (refrigerator)

2. Caramelize the Onions

   Slice the onion thinly. Melt butter in a skillet over medium‑low heat, add the onions, sprinkle sugar, and stir occasionally. Cook 20‑25 minutes until deep golden and sweet, then set aside.

   Time: PT25M

   Temperature: Medium‑low

3. Prepare Caviar Mayo Sauce

   In a small mixing bowl whisk together mayonnaise, caviar, lemon juice, Dijon mustard, and chopped chives until smooth. Chill until assembly.

   Time: PT5M

4. Dredge the Chicken

   Remove chicken from brine, pat dry, and coat each piece in a shallow dish of seasoned flour (salt and pepper). Shake off excess flour.

   Time: PT5M

5. Heat Oil for Frying

   Fill the deep‑frying pot with vegetable oil to a depth of about 2 inches. Heat over medium‑high until the thermometer reads 350°F (175°C).

   Time: PT10M

   Temperature: 350°F

6. Fry the Chicken

   Carefully lower the dredged chicken into the hot oil using tongs. Fry 8‑10 minutes, turning once, until the exterior is golden‑brown and the internal temperature reaches 165°F (74°C). Transfer to the paper‑towel‑lined plate to drain.

   Time: PT10M

   Temperature: 350°F

7. Toast the Buns

   Slice the brioche buns in half and toast cut sides in a clean skillet over medium heat for 1‑2 minutes until lightly browned.

   Time: PT2M

   Temperature: Medium

8. Assemble the Sandwiches

   On the bottom bun, layer lettuce, tomato slice, pickles, the fried chicken, a generous spoonful of caramelized onions, and a drizzle of caviar mayo. Top with the bun crown.

   Time: PT3M

Chef Tips from the Video

• For extra crunch, double‑dip the chicken: flour, dip in buttermilk again, then coat with flour a second time.
• Use a light hand when folding caviar into the mayo to preserve the delicate texture of the pearls.
• Finish the sandwich with a thin drizzle of high‑quality extra‑virgin olive oil for added richness.
