Divide the shrimp in half. Place 1 portion in a mortar and pound to a fine paste. Alternatively, chop them finely with a large, very sharp knife or cleaver and then use the flat of the blade to mash them to a paste. Form the paste into little balls, the size of marbles.
Heat water in a steamer and steam both the shrimp balls and the shrimps for 3 minutes. Remov
