To begin making the Ratalu Pakora recipe, firstly if you are using fresh yam, wash them in water and slice them into long slices. 

In a bowl, add besan flour, salt, spice powders, hing, baking soda and mix them well.

Now, add water to the flour mixture little by little and mix them with a spatula.

The batter should be thick and should be in the consistency of dosa batter. 

Meanwhile, heat oil in Wok/Kadai over medium heat. Once the oil is and reached required consistency such that a ball dropped into it rises steadily, take a slice of yam, dip it in the batter and drop it into the oil. 

Fry until they turn golden in color flipping through half way. Repeat the same for the remaining available yam slices.

Prepare this Ratalu Pakoras and serve with Dhaniya Pudina Chutney, or Tomato Chutney on the side.
