Put chicken in a bowl and season with salt and pepper. Pour calamansi juice or lemon juice and mix until the seasonings are well mixed with the chicken. Set aside.
Remove egg yolks from salted egg whites and mash the yolk until all the lumps are gone. Set aside.
To make the breading: combine flour, cornstarch, pepper, salt, paprika and garlic or onion powder. Mix until well combined.
Get a piece of plastic bag and put some of the breading and 5 to 7 pcs of chicken wings. Let some air in the bag and close it by twisting the opening.
Shake the bag with the chicken and breading until the chicken is well coated with the breading.
Heat oil in the pan about and inch deep and fry the chicken until golden brown. When cooked, put in the plate lined with paper towels to drain excess oil.
To make the salted egg yolk sauce: Melt butter in a pan and saute garlic and chili flakes until slightly brown. Add in the mashed yolk and stir until it is dissolved in the butter.
Let it simmer for few seconds then add in the fried chicken. Toss well until completely coated with the egg yolk sauce. Serve hot and enjoy!
