I once sat through a tabletop game (Shadowrun) eating a small tub of matcha icecream all to myself. …The taste isn’t actually too far off.
There’s a swirl of powdery matcha that comes off the tea and goes right through your strainer, as expected. The almond slivers and sugar really add to the vanilla icecream base, and the matcha is a nice, sweet, very ‘cooking matcha’ texture.
I picked up a bag of this after someone from my gaming group shared their stash with me. Pretty nice hot, but when I forgot it for a few hours and started sipping it again it isn’t too bad cold, either. Could make for an interesting iced tea… You’d have to shake it each time, though.
