You will need a food processor or a high-powered blender to do the job. Do not try to do this in an ordinary blender; it may burn out.
Feel free to add a teaspoon of vanilla extract when blending.
If you find the ice cream not sweet to your liking, add some sugar, honey or condensed milk when blending.
Using the same procedure, you can make your favorite flavored ice creams; nutella, coffee, chocolate, nuts, mint, other fresh fruits etc.
