If using frozen grated cassava, use a cheesecloth or kitchen cloth to squeeze it hard to remove any excess moisture. Discard the liquid.
Place the grated cassava in a large bowl and add salt and sugar. Mix well.
Heat a frying pan (flat iron or griddle) over medium heat. Then, add your oil or ghee.
Divide the mixture into 8 parts and form them into balls.
Add the cassava patties to the frying pan, then flatten the dough into circles using the back of a spoon or spatula. Make sure all the parts of the patty reach the oil.
Cook for 3-4 minutes on each side until lightly brown. You may have to do so in batches.
Submerge the fried bammy in coconut milk for 15-20 minutes. Remove them and lightly pat dry using a clean cloth or paper napkin.
Fry again or grill each bammy on both sides for another 4-5 minutes until golden brown.
Serve hot with fried fish or Jamaican escovitch fish.
