"At Grand Opening, chef Melissa Chou puts a seasonal California spin on the classic Chinese sponge cake. But, uh, you can only get a slice of it one day each month. That’s because Grand Opening is a pastry pop-up at Mister Jiu’s (a Hot 10 2017 alum!) in San Francisco, open just the second Saturday of every month. From 10 a.m. until they run out, Chou and the team sell riffs on Chinese baked goods, like wife cookies layered with quince and black sesame and chewy brandied cherry nian gao. But the one dish we can’t stop thinking about is the cloud-like Chinese sponge cake. Here Chou breaks down it comes together." - ByRachel Karten
