Preheat smoker to 225–250°F (or oven to 375°F for a simpler version).
Place the Brie in the cast iron dish and score the top like a tic-tac-toe board.
Spoon Smoke Show over the top, letting it melt into the cuts.
Sprinkle thyme evenly over the top.
Smoke for 20–25 minutes (or bake in the oven for 12–14 minutes) until molten and gooey.
Serve hot with crackers or bread. Drizzle lightly with honey and scatter the chopped pistachios over the top for crunch, color, and extra holiday flair.
