In a small saucepan, add 3 cups of water and bring to a boil over high heat. Add boba once the water boils and simmer for 4 minutes. Drain the boba and wash under cold water, and set aside.

In the same saucepan, make the syrup. Add the sugar, water, saffron, and drained boba to the pot and bring to a boil. Simmer for 7 minutes, stirring often.  Pour into a bowl and set aside.

In a small saucepan, add milk, cinnamon, cardamom pods, and salt and bring to a simmer. Turn off the heat and let it steep. Alternatively, you can heat the milk and spices in the microwave for 30 seconds- 1 minute and then let it sit for 10 minutes.

While the milk steeps make the cold foam. Add the cream, milk, sweetened condensed milk and cardamom to a small bowl and whisk until light and fluffy, about 3-4 minutes.

Strain the infused milk and set aside.

To assemble, add 3 heaping tablespoons of boba into the bottom of a tall glass. Swirl the boba in the glass so the syrup coats the sides of the cup. Fill the cup with ice and then add in 1/2 cup of the milk and top with additional milk if necessary, leaving a 1-inch top. Pour your cold foam over the milk until your glass is full. Garnish with rose petals if you like! Enjoy immediately.
