Start by pouring the full cream milk, condensed milk, and dry milk into a large pan. Bring the mixture to a boil over medium heat.
Then add cardamom to the mixture, allowing them to reach near-boiling on heat.
Mix a tablespoon of cornstarch in a separate bowl with a little water (About 2-3 spoons) to create a smooth paste. Add this to the boiling milk, which makes it thicken and gives the ice cream its unique texture.
Heat for about 10-15 minutes until the water evaporates. Then remove it from the heat once the mixture's texture thickens.
Add a pinch vanilla extract to the mixture and stir them.
Pour the mixture into your desired container and freeze it for at least 8 hours or until it's completely frozen.
Once frozen, scoop the ice cream into bowls or onto sticks.
Finally, sprinkle chopped pistachios (or whatever else you like) over the Sheer Yakh before serving.
