This is my single cup method that doesn't involve any pouring. It's basically a tea sock concept improvised from a leftover scrap of mosquito netting:

1. Heat water in a metal cup directly on the stove or fire to a little bit above drinking temperature.
2. Remove from heat, stuff 8-inch x 8-inch (about) square of mosquito netting into cup as a liner.
3. Dump grounds in, wait a few minutes, remove.

The netting leaves some grounds in the cup but it drains instantly and what's left isn't enough to affect the flavor even if you take your time drinking it. It dries very quickly. It also works well for loose tea.
