Lightly oil the inside of your tulumba tool (or piping bag with a star tip).
Fill the tool with dough.
With the oil heat turned off, test a small piece: dip scissors in oil, pipe a small amount of dough into the oil, and cut it off. The dough should sink to the bottom.
Begin frying the dough by piping it into the oil and cutting each piece to your desired size, working in batches to avoid overcrowding the pot.
Let the tulumba fry briefly, then turn the heat back on to medium.
Fry slowly, gently turning the tulumba continuously so they cook evenly.
Fry until deep golden brown (about 3+ minutes).
Turn off the heat and remove the tulumba with a mesh strainer, allowing excess oil to drip off completely.
