Ingredients:
- 1½ lb (680 g) ground beef, 80/20 or 85/15
- 1 cup (150 g) finely diced yellow onion (about 1 small onion)
- 1 tbsp (9 g) minced garlic (about 3 cloves)
- 1 tsp (5 ml) neutral oil (only if using 90/10 beef)
- 2 tbsp (16 g) chili powder
- 2 tsp (4 g) ground cumin
- 1 tsp (2 g) smoked paprika
- 1 tsp (2 g) dried Mexican oregano
- 1¼ tsp (6 g) kosher salt, adjusted to taste
- ¼ tsp (1 g) ground black pepper
- 2 tbsp (32 g) tomato paste
- ½ cup (120 ml) water
- 1 tsp (4 g) brown sugar
- 1 tbsp (15 ml) fresh lime juice
Instructions:
- Dice the onion, mince the garlic, and combine the spices in a small bowl. Measure the water and lime juice and set them within reach.
- Set a 12-inch skillet over medium-high heat for 2 to 3 minutes, until a drop of water sizzles and evaporates instantly. Add 1 tsp oil only if using 90/10 beef.
- Add the beef in one layer and press it flat. Leave it undisturbed for 5 to 6 minutes, until a deep brown crust forms on the bottom and the edges are crisp and lacy. If the beef sticks, give it another minute.
- Break the beef into crumbles. Tilt the pan and spoon off most of the fat into a heatproof bowl, leaving about 1 tbsp (15 ml) in the pan. Cook until no pink remains and the internal temperature reaches 160°F (71°C).
- Cook 2 to 3 minutes more, until the sizzle quiets and the crumbles look dry and browned rather than wet.
- Add the diced onion and cook 3 to 4 minutes, until translucent and the edges begin to color.
- Stir in the garlic and cook about 30 seconds, until it smells sharp and sweet, not bitter.
- Add the spice blend (2 tbsp chili powder, 2 tsp ground cumin, 1 tsp smoked paprika, and 1 tsp dried Mexican oregano), the black pepper, and the tomato paste. Stir about 1 minute, until the spices smell toasty and the paste darkens to a brick-red color.
- Pour in the water and scrape up the browned bits from the bottom of the pan. Add the brown sugar and stir until dissolved.
- Reduce the heat to medium-low and simmer 3 to 5 minutes, until the sauce looks glossy and coats the meat without pooling.
- Remove the pan from the heat, stir in the lime juice, and taste. Add salt in small pinches until the flavor pops. Serve immediately.
