Suggestion:-
Take 1 tsp ghee in a wok and allow it to melt on medium flame. When ghee is melted add sugar into it and stir constantly. Keep stirring constantly and cook until sugar dissolves completely.
When sugar is melted, reduce the flame to minimum and add chana into it. Mix really well.
Now grease back side of a plate with some ghee. Pour the mixture over plate and spread it evenly. Grease the rolling pin with some ghee and roll the mixture evenly or use spoon for spreading the chikki evenly.
When it gets frigid, separate out the chikki from plate with help of knife.
Chana chikki is ready. When chikki gets frigid, break and store the chikki in air tight container. This can be stored for upto 6 months and eat whenever you like.
