The Base Assembly: Dice your fresh bell pepper, jalapeño, shiitakes, and mince the garlic. In your Dutch oven, combine all the canned goods (draining only the corn), the fresh peppers, shiitakes, minced garlic, dehydrated onions, cumin, and the remaining chili powder. Stir gently.
The Meatball Formation: In a bowl, gently mix the ground beef with 1 tbsp chili powder, 1 tsp garlic powder, salt, and pepper. Form it into a large, slightly flattened ball. The Science: Keeping it flat increases the surface area for maximum smoke adhesion (Maillard reaction) and provides a wider drip radius over the pot.
The Kettle Geometry: Set up your Weber Kettle with a snake method for 250°F. Place the uncovered Dutch oven on the indirect side. Place your wire rack over the Dutch oven, and place the seasoned meatball directly centered over the pot.
The Smoke Phase: Add wood chunks (oak or hickory) to the coals. Close the lid and maintain ambient temps. The Science: As the ambient heat renders the 80/20 beef, gravity pulls the smoked tallow directly into the chili base. This hot beef fat breaks down the chitin walls of the shiitakes, extracting their flavor into the stew.
The Thermal Pull: Smoke the meatball until the internal temperature reaches 150°F (roughly 1.5 to 2 hours).
The Crumble & Integration: Once the beef hits 150°F and has a dark mahogany bark, transfer the meat to a cutting board. Chop and crumble it, then stir the smoked beef directly into the Dutch oven.
The Simmer: Move the Dutch oven over the remaining coals. Let the integrated chili simmer for another 30 to 45 minutes until the beef safely reaches 165°F and the liquid reduces to a thick, glossy consistency. Simmer longer as needed.
