Heat a skillet over medium heat.
Once hot, add in the ground beef. Cook until browned and mostly cooked through.
Whisk together all spices, salt, sugar and cornstarch.
Add in the spice mixture and stir to combine.
Add in the water and mix well. Reduce the heat to medium/low and let simmer. It might seem liquidy at first and this may be more water than you're used to using for ground beef, but I promise it works! It will thicken and make the beef much more flavorful.
Let simmer for about 10-15 minutes or until the liquid is absorbed. Taste and add more salt or some cayenne or red pepper for spice.
Warm your tortillas either in the microwave or on the stove (this will help prevent cracking/ripping), then top with the beef, lettuce, pico, cheese and crema. Enjoy!
