Instructions

  1. Step 1: In a small saucepan, combine 1/2 cup apple cider vinegar, 1/2 cup water, 2 tbsp granulated sugar, and 1 tsp kosher salt. Bring to a simmer over medium heat, stirring until sugar and salt dissolve. Pour over 1 medium thinly sliced red onion in a heatproof bowl. Let cool to room temperature, then refrigerate for at least 30 minutes to pickle.
  2. Step 2: Warm 2 tbsp butter in a skillet over medium heat. Lightly toast 4 soft sandwich buns cut side down for 2 minutes until golden.
  3. Step 3: Reheat 1 lb thinly sliced smoked beef brisket gently in a pan or microwave until warm.
  4. Step 4: Spread 1 tbsp yellow mustard on each bun bottom, then layer with 1/4 cup homemade barbecue sauce and a generous portion of warm brisket.
  5. Step 5: Top brisket with pickled red onions (about 2 tbsp per sandwich), then cover with the bun tops. Serve immediately.
