First powder the pottukadalai in a mixie and sieve it(not shown in picture). You can powder more than needed and store for future use.
Heat required oil in a kadai. Mean while you can make the dough. Place all the ingredients in a mixing bowl, mix well. Add hot oil from the kadai and mix well. Add water gradually and carefully to make a smooth dough.
I used the regular 3 eyed thenkuzhal plate for this, you can use the star shaped ones too.
Fill the press ¾th with the dough and squeeze it either directly over the hot oil or over few greased ladles and then carefully flip to the oil.
I did the later as I cant handle the heat when we squeeze over the hot oil as steam will be too hot.
Also squeezing in ladle then transferring aids good shape. I always do this from the beginning which I learnt from my MIL.
Make sure oil is hot enough by checking dropping a small piece of dough, it should come up immediately.
I fried 3 at a time. Cook both sides until golden in color in medium flame. Shh sound should cease and bubbles should be reduced.
Drain in paper towel and cool down before transferring to the airtight container.
