Sandesh is a dessert, originating from the Bengal region in the eastern part of the Indian subcontinent, created with milk and sugar.
In a pan, heat 1 cup milk, add little water and let it boil.
Remove the milk in a bowl, add 2.5 tsp lemon juice and stir continuously with a spoon.
The milk will start to curdle. After it curdles, strain the mixture using a cloth.
Transfer the strained extract into a bowl, add 1 tbsp powdered sugar and 1/8th tsp cardamom powder.
Mix it well and bind it into a round shape and add 1/2 tbsp chopped pistachios on it.
Sandesh is ready to serve.
