Steam cook maida for 10mins (I laid a white cloth inside the container then added the flour). After 10mins - When you take it, it will have lumps formed as shown.
Cool down and break the lumps formed and spread it in a plate and leave it to cool down for 2hrs until it is completely dry.
Then sieve it and collect it in a container, now the flour for murukku is ready. You can even grind the coarse flour remaining and then sieve it again (I didn't grind it as most of them were sieved fine).
In a mixing bowl, add maida, butter, sesame seeds, required salt and mix it once. Then add hot water and combine.
Combine to form a smooth dough. Then divide them equal portions and set aside. I used the star shaped press for the murukku.
Grease the murukku press(it is like cookie press) and add the dough till it fills 1/2 to 3/4th of the murukku press. Then press it circular to form a pattern.
Form a pattern like shown below at the back of a ladle (slightly grease it with oil). Heat oil in a kadai (as required for the murukku to immerse fully) - carefully flip the ladle and drop the murukku in oil.
Cook the murukku on both sides till the 'shh' sounds ceases and they turn golden brown in color (Fry it in medium low flame). Drain in tissue paper and then store in an airtight container.
You can store it in an airtight container for weeks and enjoy Mullu Murukku.
