Place the eggs in a medium sized saucepan with cold water.
Bring to the boil then reduce to a simmer for 10 minutes or to your prefernce (see the notes).
Once boiled drain off the water and immediely transfer the eggs to cold water to halt further cooking.
Peel the eggs when they are cool then set aside.Place the cassava in a medium sized saucepan with cold water and 1 teaspoon of pink salt.
Bring to the boil and cook for 15-20 minutes or until the cassava is fork tender and easy to crush (test the readiness with a fork). It should be really soft and the colour of the cassava should be translucent and not obaque.
Once cooked, drain off the water.
Immediately transfer the cassava into a medium sized bowl with a small amount of leftover hot water (equavalent to afew tablespoons).
While the cassava is still hot, use a fork or potato masher to crush the cassava until it is smooth and lump free.
Add the onion granules, garlic granules pink salt and then scallion (if you are using).
Continue to mash the cassava so the add in ingredients are incorporated (make sure the scallion isn't sticking out as it will burn when frying) by now it should be firm and can hold its shape (you can form it into a dough if you want to).
Do a taste test of the mixture and add aditional seasoning if needed.
Coat the palm of your hand(s) with olive oil then add about ⅓ cup worth of the cassava to the centre of your hand.
Roll the cassava into a ball then flatten it into a disc.
Place the egg directly in the centre and bring the cassava round so it is encasing the egg.
Gently roll to create a smooth ball with no cracks or gaps.
Repeat the above 4 steps with the rest of the cassava.
Heat olive oil on medium heat in a small non stick frying pan, make sure the oil is hot before proceeding with the next step.
Once hot, add one of the egg balls, frying one side at a time, making sure to move the pan in a back and fourth and side to side motion.
Also baste the ball with the hot oil and continue to cook until golden brown.
Once done, place the ball on some kitchen towel and repeat the above 2 steps
