Boil milk in a heavy bottomed pan and simmer it until it reduces from the original quantity for 10 minutes. In the meantime, take corn flour in a bowl. Add 2 tablespoon of milk to it.
Mix corn flour and milk without any lumps. Set aside. Once the milk is slightly thick, add sugar. Mix well.
Then add cornflour milk paste to the milk and heat it further for 5 more minutes with occasional stirring. Switch off the flame once done and cool it down.
Take fresh cream in a freezer safe container(freeze the container before 10 minutes of use) and beat it well until its soft. Once done, add milk sugar corn flour mixture to it and mix well.
Wash the strawberries in running water thoroughly. Place it on a cutting board and slice the stem off the fruit. Then slice the fruit vertically or horizontally.
Then take the chopped strawberry pieces in a juicer/blender. Blend everything till smooth.
Then transfer the blended strawberry puree into the same freezer safe container where we have added fresh cream milk mixture. Mix everything well without any lumps.
Now Place the container in a freezer and freeze it . After 2 hours, take the container from the freezer.
Transfer the contents to a blender and blend again to a smooth paste. Do repeat this every 2-3 hours to get a smooth consistency. Repeat the blending and freezing at least 3-4 times.
Then freeze it overnight or scoop out the ice cream after 4-5 hours. First it will be like a hard crystal, after 10 minutes it will be smooth.
