In a large saucepan, add the water, ginger, peppercorns, cardamom, cinnamon, cloves, star anise, nutmeg, and chopped dates.
Bring to a boil, then reduce heat and let it simmer for 10–15 minutes so the flavors and sweetness fully develop.
Add the tea and simmer for another 3–5 minutes.
Pour in the milk (along with the saffron and its soaking milk if using) and bring it gently to a boil again.
Strain the chai through a fine mesh sieve into cups or a teapot.
Serve hot and enjoy the comforting blend of spices and natural date sweetness.
