Place yam fries in pot, cover with water and bring to the boil over high heat. Reduce heat and simmer until yam is cooked through. Make sure it is not too soft or it all goes mushy. Mine took about 10 mins of simmering.

In a large bowl, mix flour and water together into a paste before adding in the egg, pepper and salt. Gently mix in the yam fries and coat them with the batter.

Heat the oil on medium high heat until it is hot enough for deep frying and using a spoon, scoop one yam fry at a time along with some batter and drop into the oil. Don't put too many in the pot at the same time. Fry until golden, turn them over and repeat on the other side.

Remove yam fries from the oil unto paper towel to drain the excess oil, store in a warm place and cook the rest of the fries.

Serve warm with a chilli or peanut butter gravy.
