Bring water to a boil in a heavy saucepan.
Add Kashmiri green tea leaves and lightly crushed cardamom pods. Optional: add a small cinnamon stick or 1 star anise.
Reduce heat and simmer until the liquid is about half and deeply aromatic.
Stir in a pinch of baking soda; continue simmering until you see a reddish/pink foam forming on top, whisking or stirring occasionally.
Add a glass of ice-cold water, turn the heat to high, and aerate by ladling the tea from a height back into the pot for 1–2 minutes to develop color.
Test for color by mixing a spoonful of concentrate with a little milk in a cup; if it turns pink, proceed. If not, simmer and aerate a bit longer.
Add whole milk to the pot, just enough to make the tea dusty pink (the qty of milk needed depends on strength of tea mixture) Bring to a gentle simmer so the flavors marry.
Strain into cups. Add salt to taste or make it sweet using to sweetner. Add crushed pistachios and almonds
