Ingredients for Grilled Pork Shoulder With Butter Vinegar Sauce

  • 1 tablespoon fennel seeds

  • 2 tablespoons dried oregano

  • 2–2 1/2-lb. boneless pork shoulder (Boston butt)

  • Grapeseed or other neutral oil (for pork)

  • 1 tablespoon kosher salt, plus more

  • 3 chillies de árbol, torn in half, seeds removed if desired

  • 120ml apple cider vinegar

  • 120ml (1 stick) unsalted butter

  • 2 tablespoons sugar

  • Special Equipment: A spice mill or mortar and pestle

Toast fennel seeds in a dry small skillet over medium heat, tossing often, until golden brown and starting to pop, about 3 minutes. Transfer to a spice mill or mortar and pestle and let cool; coarsely grind. Transfer to a small bowl and mix in oregano. Place pork on a wire rack set inside a rimmed baking sheet and rub with oil. Season all over with 1 tablespoon salt, then rub with spice mixture, packing it on. Let sit at room temperature 2 hours or chill, uncovered, up to 2 days.

Bring chillies, vinegar, butter, and sugar to a simmer in a small saucepan over medium-high heat; cook, stirring occasionally, until sugar is dissolved and sauce is reduced by about a third, about 5 minutes. Season with salt; cover and keep warm over low heat until ready to use.

Prepare a grill for medium heat. Drizzle pork all over with oil, then grill, turning every 5 minutes or so, until extremely, gorgeously browned and crisp and an instant-read thermometer inserted into thickest part registers 49°C, 35–45 minutes. Continue to grill, brushing with sauce and turning not quite every minute (you’re going to see flare-ups, but don’t worry), until pork is glazed and shiny and temperature on thermometer has risen to 54°C, 5–10 minutes more. Transfer pork to a platter and let rest 30 minutes; reserve remaining sauce.

Transfer pork to a cutting board and pour any accumulated juices on platter into reserved sauce. Return sauce to a simmer. Slice pork against the grain 1/4" thick. Arrange on platter, spoon some sauce over, and season with salt. Serve remaining sauce alongside.

If using a charcoal grill, a bed of medium-hot coals will gradually lose heat. Get a chimney started when the meat first hits the grill. About halfway through, throw some new glowing coals on the pile to keep things going.
