This is a chai blend that features star anise as one of the stronger flavors. You need a spice grinder or a really clean coffee grinder for this.
1/2 cup whole star anise or 1/3 cup ground star anise
1/4 cup cardamom seeds
2 tbsp ground cinnamon
2 tbsp ground ginger
1 tbsp black pepper
1 tbsp ground cloves
1 tbsp nutmeg
This makes a little less than a pint, but more than a cup.
Assam tea for blending.
Instructions: grind the whole spices in the grinder and transfer to a jar. Once all the spices are in the jar, shake it up so they blend together.
What I did at this point was get a smaller jar and fill it 1/3 of the way up with the spice blend, and then the rest of the way up with assam tea leaves. This is about the ratio you want of spices to tea, but you can store the spice blend separately and just mix it with whatever tea you have on hand as you go, though I do recommend assam or another similarly strong black tea like orange pekoe or ceylon.
