Place the ground beef in a skillet over medium heat with a splash of water. Let it cook until the water is mostly absorbed.

Add a splash of oil and cook the beef for a couple of minutes.

Blend the onion, tomatoes, and garlic (you can mash the garlic first with salt and cumin if you like) with a little water. Add this mixture to the beef.

Pour in 2 cups of water. Let it heat up, then add one bouillon cube. (Add salt to taste.)

Bring to a boil and add the carrots, diced into small cubes. Cook for 5 minutes.

Finely chop the serrano pepper with a knife or fork and add it to the pan.

Add the cilantro, corn, and potato. Let the potato, diced into small cubes, cook for about 10 minutes.

Turn off the heat and let it rest for 5 minutes.
