Firstly, in a large thick-bottomed pan heat milk.
Add sugar and stir continuously so the sugar dissolves completely.
Now add ½ tsp alum powder (fitkari powder) to the milk. Stir and allow the milk to curdle.
Stir continuously as the milk splutters. Milk starts to thicken and water evaporates from it.
Then on another side in a pan add ½ cup of sugar and caramelize it. When sugar is completely caramelized and turns brown color then add to the milk mixture.
Stir the mixture till the milk mixture thickens and start to separate the pan.
Add cardamom powder and mix well.
Switch off the gas and allow it to cool the mixture completely.
Finally, with greased hand make a round shape peda or set it into block shaped burfi. Garnish with slits of almonds and serve.
