When fragrant and lightly browned, add water and allow it to boil.
Once boiling, add the tuna and fish cube. Allow the tuna to fully cook and the fish cube to dissolve.
Once the tuna is fully cooked, season to taste with salt and pepper.
Right before serving, add the sili leaves, scallion pieces, and long chili peppers. Do not cook these for too long as it will dull the flavor of the ingredients.
Drizzle with patis and serve with freshly-steamed rice.
