1/4 cup sugar (adjust to taste)
1/4 tsp cardamom powder
1/4 cup chopped nuts (almonds, pistachios, cashews)
2 tbsp warm saffron soaked milk or orange food color
2 tbsp pistachio paste or green food color
Bring milk to a boil. Reduce flame and let milk simmer. Add sugar and cardamom powder. Once rabri thickens, remove from heat.
Divide rabri to three parts. Mix saffron or orange color in one and pistachio paste or green color in another. Keep one portion plain.
Add base layer in glass, set in fridge then add another layer. Repeat freezing and layering to make tricolor display.
Garnish rabri with dry fruits and nuts. Set in the fridge and serve.
