Heat a pan, add ghee, and then add cardamom powder.
Add suji/rava, and roast it for about a minute or so till it gives out nice aroma.
Add milk and stir for about a minute till the mixture thickens a bit. (The mixture should be runny as you will be adding bananas to it later.)
Meanwhile, peel the bananas, and cut 2 bananas in small (approx. 1 cm) pieces. Kalpesh cut four slices to decorate the sheera and then cut the remaining bananas in small pieces. (Mash the bananas if you are making this sheera for babies or toddlers who may not be able to chew the pieces while eating sheera.)
Cut other 2 bananas and grind to a thick paste using a mixer. (Do this just before you need to add this paste to suji as bananas will blacken if you keep them aside for some time.)
Add the banana paste and chopped bananas after switching off flame.
Stir in the bananas so that they get mixed in sheera properly. (Don't cook sheera after adding banana otherwise its taste gets affected.)
