Pure anal beads. If you put the milk in first you run the risk of making it too milky. And if you put too little in you run the risk of making it too strong, thus having to put milk in afterwards anyway!
Personally the tea I make, which is The Shit if I say so myself doesn't tase like hot watery milk, what teabags do you use? I use the PG Tips pyramid bags, MORE ROOM TO INFUSE! then add the milk and rape the teabag for your desired shade of tea.
