Liquidize the prawns in a blender until they form a
smooth paste. Transfer the prawn paste into a bowl
and mix in the tapioca flour, salt and pepper. Mix
well to form a stiff dough.
Divide the dough into
3 equal portions. Roll up each portion then place
the rolls on a greased plate. Place the rolls on a
stand in a pan of boiling water
or in a steamer, and steam for 40 to 45 minutes
over a high heat.
Leave the rolls to cool, then
wrap in a clean tea towel and chill well in the
refrigerator.
Use a very sharp knife to slice
thinly.
Heat the oil in a deep wok and deep-fry
the crackers in batches until crisp.
Remove from
wok and drain on kitchen paper. Serve hot or cold.
