Ooh I wish I had thought to blend this with the Java Momma Green Daydream, both from the Strange VariaTea TTB! It has an almost chocolate-y roast, which might go really well with the vanilla of that tea. I might add some Daydream to the resteep.
ETA: I did try that, but it didn’t really live up to my hopes – possibly the ratio was off? The houjicha overwhelmed the marshmallow vanilla of the Daydream.
