I associate Zen with Green Tea...the froth of the liquid Jade...as it was called.
In my working life, before I retired, I've worked in countries where both Tea and coffee were big items.
When I worked in Turkey I remember getting up very early...about 3 in the morning ...for trip a trip to another city.
About 6 a.m. we were halfway there and stopped at a little roadside shop in a small Turkish village.
We had tea and fresh baked rolls with honey. In Turkey you drink tea from a small shot-glass, poured boiling hot from the pot. No sugar in the Tea, but you get one or two sugar cubes on a plate with your tea. You place one of the sugar cubes between your teeth and sip the very hot tea letting the sugar cube slowly dissolve in your mouth with the tea. Often they also give you a slice of lemon, which you squeeze into the tea before you drink it. At least this was how it was done then outside the big westernised cities in Turky around 1990...not sure if it is still the custom now.
By the way, just to continue the "tourist" stories, I actually visted Konya to see the Sufi's dance, they were incorrectly called the "whirling dervishes" by the first Europeans who saw them. It was a tourist thing around 1990, but I'm not sure they still do it. Turkey has changed drastically since 1990.
Then when I was in the mideast, Saudi Arabia to be exact, if you went into a shop to buy something they would absolutely insist of serving you small china cups of dark, bitter and strong, Arabic coffee before they wanted to talk about price. It just wasn't polite not too offer that coffee before talking price.
So both tea and coffee both hold memories for me.

Shame on you Shakyamuni for setting the precedent of leaving home.
Did you think it was not there--
in your wife's lovely face
in your baby's laughter?
Did you think you had to go elsewhere (simply) to find it?
