Wash the ginger, cardamom, star anise, cloves, peppercorn and cinnamon. Dry these as much as possible before the next step.
Mix the ginger, cardamom, star anise, cloves, peppercorn and cinnamon together. Dry roast as needed over low heat without any oil or ghee until the moisture is removed from the ingredients. If you are using already dried ingredients, you may skip the roasting stage unless the ingredients are still moist or have been sitting a while.
Grind the mix up into a coarse powder to ensure the mix infuses evenly. Don’t make the powder too fine. You could use a blender or a coffee grinder to do so.
Mix this coarse powder into the tea leaves ready to steep.
OPTIONAL: Add crushed stevia to give the chai sweetness without needing to add honey or sugar at a later point. This can be good if you are on a restricted sugar diet.
Store in an airtight container for use as needed. You can do so loose or add a teaspoon to individual teabags if you prefer.
