Mash the fish, in a pan add in little oil, add in chopped onions, garlic, curry, ginger and thyme and stir, then add in the mashed fish and stir fry for 5 minutes and set aside.

In a large bowl, add the flour, baking powder, sugar, salt and margarine into the flour until it comes out crumbly. Add the egg and mix it with the flour until it is totally absorbed by the flour. Begin to add the water a little at a time until a workable dough is formed.

Transfer the dough to a work surface and knead for about 3-5 minutes, then cover up the dough and let it rest for about 10 minutes. Roll out the dough to about 1/8th inch thick, then cut it out into small rectangles.

Take each of the cut out rectangle and fill it with 1to 1-1/2 tbsp of fish then tightly roll the dough and secure the tips a little bit to prevent the fish from spilling into the oil. Fry the fish rolls in preheated oil until it's golden brown. Enjoy!
