Mix the flour and dahi to form a thick smooth paste (dropping consistency), adding water if necessary and leave to ferment for 6-7 hours (time depending on the weather).

When the batter is ready, it should be spongy and you should be able to see bubbles on the surface.

Make the sugar syrup by dissolving sugar and saffron in the water over low heat, then cook over high heat till slightly thick.

When this mixture is lifted with a spoon and poured back into the pan, it should fall in a thin smooth stream, or when a drop of it is cooled a little, press it between your thumb and forefinger and then pull the fingers apart, it should be thread-like. Keep warm, till you fry the 'jalebis'.

Take a shallow, heavy pan and heat the ghee/oil. To taste if your oil is ready, drop in little bit of batter in the oil, and see if it comes up at once. If it does, your oil is ready for frying.

Fill the bag with the batter. Twist the opening to seal the bag. Snip one lower corner of the bag to make a small hole, through which you can pipe out the `jalebis'. The smaller the hole, the thinner the jalebis.

Hold the bag over the hot oil and pipe out swirls (like whirlpools), of the desired size, straight into it. Make as many such rounds as come in comfortably without touching each other.

Lower the heat to medium and turn the 'jalebis' over and fry till a light brown on both sides.

Lift out the fried jalebis, drain out the oil and put them into the syrup. Leave it for a minute or so, and then again lift it out.

Serve it hot.
