Heh. I do warm the vessel, but not in this elaborate way - just hot tap water for a half a minute. After the steeping water comes to a full boil, I let it come down a couple of degrees before adding it to the grounds in the warm press, and let it steep 4-5 minutes before pressing. And I use a lot of grounds. I don’t like infamous hogwash, either.
I wonder if Killick filtered his brewed coffee, or if he just served the coffee with the grounds swirling around in it.
