Over the last two years, I've developed a strong liking for matcha after first discovering it at the Canary Wharf branch of EAT. (In 2011 I set myself the goal of trying every variation of every warm drink in popular London coffee shops.)
Matcha, if you've not heard of it before, is a finely ground green powder made from green tea leaves. In Japan it is something of a delicacy and is normally served as part of an elaborate tea ceremony. In the west, it is commonly mixed with warm milk to produce a 'matcha latte'. It is relatively expensive because production of matcha is very slow, about 30 grams per hour according to Wikipedia.
Matcha varies in quality - the most expensive and highest grades have a much more intense flavour than cheaper variants. I've been experimenting with different sources of matcha, including from eBay (not good), from a variety of shops in San Francisco (very good) and from a variety of shops in London's Chinatown. The best I've found is from the Japan Centre in London.
It can be made into a variety of drinks, I normally either mix it into a protein shake or with milk (and a spoonful of Milo to sweeten slightly). It also makes a great baking ingredient and to date I've made a matcha trifle (rather like tiramisu), matcha, pistachio and white chocolate brownies and matcha rusks.
Fuck Yeah, Matcha! is a particularly favourite Tumblr of mine - they showcase beautiful photos of matcha based food and drink.
Matcha is also great for sufferers of thyroid disease like myself because it has a much lower fluoride content than tea and coffee. It also has a much longer half life - similar to green tea, so there are no unpleasant headaches in store. My favourite description of matcha's effects comes from Breakaway Matcha:
"The caffeine hit of an espresso can be a bit like having an express train screaming through the middle of your body: a deep, powerful, jittery roar. I find the effects of matcha to be just as stimulating but in a more delicate, refined way, as if a thousand butterflies have descended on my body, beating their wings until I'm lifted, gently but resolutely, a few inches off the ground. (Seriously.)"
My latest project has been to try and catalogue all the places that serve matcha in London. The map below is publicly editable - click here to add to it.
