It's easy dude. Go to your local Japanese Market and get yourself a good bottle of sake. Pick up a few Sapporo's while you're there.

Go home.....put the sake into a tea pot. Heat up some water and place the tea pot filled with sake into the hot water. Just be careful that you don't let water overflow into the pot. Once heated. Pour sake into small shot glasses....pour the frosty Sapporo into a large mouth glass.....drop the shot of Sake in the glass....and down that shiet.
