In a pan, put water, cooking oil, salt and annatto powder. Bring to a boil. If you are using annatto seeds, put the annatto seeds in a small metal strainer and soak it in the water while boiling. Then remove it after 1 to 2 minutes.
Put the rice flour in the pan then stir with a wooden spatula or spoon. Stir until the water is absorbed by the rice flour and continue mixing until it forms into a dough and dry to the touch. Remove from heat and cool.
Knead the dough until smooth and divide the dough into six equal parts and form into balls. Set aside.
In a pan, heat oil and saute garlic and onions until fragrant. Add the longganisa and saute until cooked. Season with salt and pepper to taste.
To assemble the empanada; Arrange the ingredients in separate bowls or containers; the longganisa, grated papaya, eggs, and dough. Lay a piece of the wax paper on a flat surface and put a dough ball(brush some oil on the wax paper and the dough). Put another wax paper on top of the dough and flatten it with your palm. Then roll it with a rolling pin until flattens into a circle and about 1/8 inch thick. Similar to making a thin crust pizza dough.
Remove the wax paper on the top surface and fill it in the center with some grated papaya and longganisa, about 1 1/2 tablespoons of each of the ingredients. Make a hollow space on the center of the filling and crack a raw egg on it.
Immediately fold the empanada into a semi circle shape and seal the edges. You can use a plastic plate to trim the edges and make a nice rounded edge. Do the same to the rest of the ingredients. Deep fry the empandas until golden brown and crisp. After cooking, place on a wire rack or paper towels to drain excess oil. Serve hot with sukang iloko as a dipping sauce. Enjoy!
