Make a paste of this using very little water. The paste should be very smooth.
Add half a tsp of fennel seeds into this and using your hand, start whipping it.
You can also use a hand blender or an egg beater. If you feel, you need to add a little more water, do so but very slowly.
The batter needs to be thick enough to make dumplings into the oil
While this is getting ready, also prepare the syrup.
In a large saucepan, take 2-3 cups of water and add sugar to it. Let the sugar dissolve, then add the gur. Keep boiling this for 3- 5 mins or until you get a single thread consistency. It should be sticky but a runny sauce. Add more water if needed.
Now keep the syrup covered and when you start making the dumplings, put it back on low heat, keeping it covered.
Heat oil for deep frying and using you fingers, scoop out little portions of the batter and drop in the oil. You will know that the boras have been whipped right if they float and not sink to the bottom
Once they have been fried golden, take them out and drop them in the hot oil.
Let them soak in the syrup. You have to cut up one and check if the syrup has gone in or not. If not, then either your batter has not been whipped right, or your syrup is too thick or the syrup is not warm enough
