Grind the green corn cobs in a blender with a little water until you obtain a homogeneous mixture.
In a pan, place the crushed corn and add butter, milk and sugar.
Cook over medium heat until the mixture thickens and takes on a porridge-like texture.
Add condensed milk and cream, mix well and cook until you get a creamy consistency.
If desired, add vanilla essence to enhance the flavor.
Beat the cream until it reaches a whipped cream consistency.
Gently incorporate the whipped cream into the corn mixture, ensuring a creamy dough.
Transfer the mixture to a container and place in the freezer until it hardens and forms ice cream.
