Pork Carnitas Tacos

In a medium bowl, combine sliced onion, vinegar, 2 tsp sugar, ½ tsp salt, and 1 TBSP water. Stir until sugar and salt are mostly dissolved. Set aside, stirring occasionally, until ready to serve.

Heat a drizzle of olive oil in a large pan over medium-high heat. Add pork and season with salt and pepper. Cook, breaking up meat into pieces, until browned and cooked through, 4-6 minutes. Transfer to a plate and set aside.

Heat another drizzle of olive oil in same pan over medium-high heat. Add poblano and chopped onion; season with salt and pepper. Cook, stirring, until softened, 3-4 minutes. Return pork to pan along with Fajita Spice, stock concentrate, half the tomato paste (use all for 4 servings), and ¼ cup water (⅓ cup for 4). Cook, scraping up any browned bits from bottom of pan, until mixture is thickened and saucy, 1-2 minutes.

While filling cooks, in a small bowl, combine sour cream, a squeeze of juice from lime half to taste, and a pinch of chipotle powder (add more to taste if you like things spicy). Stir in water 1 tsp at a time until mixture reaches a drizzling consistency. Season with salt and pepper. Wrap tortillas in damp paper towels and microwave until warm and pliable, 30 seconds.
