Plenty has already been written about Starter Bakery’s remarkable, world-beating kouign amann (pronounced something like “Queen Iman”). Suffice it to say the hockey-puck-sized pastry — a distant, slightly sticky cousin of the croissant — is dangerously habit-forming: crisp and chewy, salty and sweet, and luxurious in the way that things made mostly of butter and caramelized sugar are.
If you’re a Bay Area cafe-goer, chances are you probably already know two or three different places that carry them. But maybe you didn’t know this: Oakland’s Highwire Coffee Roasters now sells an espresso custard kouign amann — decadence on top of decadence. Following a tip on Chowhound, I headed over to Highwire’s Rockridge Market Hall retail shop (5655 College Ave.) to check it out.
