First of all, Sieve the All purpose flour / Maida and keep it aside.
Now take a big bowl and put Clarified Butter/Desi Ghee in it. Add the ice cubes and start whisking them together until the ghee turns to a cream like consistency. Now remove the ice cubes and whisk the butter until its smooth. See Video below.
Now start adding all purpose flour and milk to it in small amounts and whisking them regularly so that there is no lumps made.
Once all the milk and flour is mixed, start adding water slowly with regular whisking again. Make a smooth running consistency batter by using all of the remaining water. Now add lemon juice and whisk it properly again. Lemon juice helps in binding the flour mix while frying.
Take a round deep and flat bottomed Pan / Kadhai and fill more than half of it with ghee. Heat it on high flame till the ghee gets really hot. You can check the correct temperature by dropping a small portion of the batter and see if it immediately comes up, and doesn't stick to the bottom.
Once the ghee is hot, take ladle full of batter and pour it in the middle of the pan in a thin stream. After pouring ladle full batter, wait for at least one minute till the bubbles settles and then pour the second batch.
Repeat the same process for 3-4 times depending on the size of ghevar, you want. When pouring the batter into the centre of pot, it spreads around the corner and lift up in the ghee. Keep making space in centre by using a skewer/round stick to pour more batter after the previous batch has settled.
Pour little batter on the sides of pan too to make it perfect round. Once you have poured enough batter, let the ghevar fry for few good minutes till its golden brown in colour. Try to rotate your ghee in the pan / kadhai while frying which helps in evenly frying of the ghevar.
Once its fried properly, take it out very carefully by inserting that thin skewer/stick in the middle hole and lifting the whole ghevar with it.
Keep the ghevar slightly tilted on a plate to remove excess oil. I hanged it with the help of skewers and taking support of two tall glasses.
