If you want to add tea (sometimes I add black tea), just let it steep for the normal duration after cooking the rest and before adding the orange juice and honey. For the best result/taste you should grind the spices right before cooking. (Pre-)ground spices work to; you might use a little bit more of them. A word of warning on the pepper: use very little at first. Cooked it the water it is a lot hotter/more stinging than you might expect.
