reduce the flame to its lowest and slowly pour milk in the pan. mix very well.
simmer milk on a low to medium-low flame. stir ocassionally so that the milk or seviyan does not stick to the bottom of the pan.
let the milk come to a boil. once the milk comes to a boil, then add 7 to 8 tablespoons sugar or as per taste.
mix very well so that all the sugar dissolves.
next add 10 to 12 saffron strands. mix and stir.
next add 1 tablespoons of sliced almonds and 1 tablespoon chopped cashews. mix well.
then add ½ teaspoon cardamom powder.
also add 4 to 5 dried rose petals. this step is optional. skip if you do not have dried rose petals.
cook the vermicelli kheer mixture for 4 to 5 minutes more till the seviyan gets cooked and the milk thickens. when the seviyan has softened and cooked well, the kheer will also thicken and look creamy.
switch off flame and then 1 tablespoons raisins. mix again. check the taste of vermicelli kheer and if required you can add some more sugar.
serve the vermicelli kheer hot, warm or chilled. you can garnish with some chopped nuts or dried rose petals while serving. do note that on cooling the kheer will thicken.
