Cut the pork, onion, potato, and carrot into bite-sized pieces.
Heat cooking oil in a pan and stir-fry the pork.
When the pork is cooked, add the onion, potato, and carrot. Stir-fry together.
Once all the ingredients are somewhat cooked, add water and bring to a boil.
When the vegetables are cooked, add curry powder and mix well.
Simmer over medium heat until the curry thickens.
Serve the pork curry with rice on a plate to finish.
