I gave Miette in the Ferry Building market a second chance today at lunch and was unfortunately disappointed. A while back I tried them out when they were at the farmer's market further up the Embarcadero. The tea cake I tried was flavorless and undercooked. I called them up to mention it and was offered a free cake the following weekend, but that one was also undercooked. Just looking at it's misshapen top should have been a clue to the baker.
I tried them out again today and went with a simple vanilla cupcake with chocolate buttercream frosting. The cake was dry and a tad tough. The frosting was remarkable in that it had such little flavor I wondered exactly how they did it. At $3 a pop, they're definitely not bargains especially given their minute size. i give them a 3 out of 10. Nothing at all like Magnolia or other cupcake bakeries in NY. I prefer any old supermarket over Miette.
On a more positive note, the twice baked brioche from Lulu Petite is worth trying. I believe the brioche is baked once, and then filled with marzipan and other goodies before a second baking. i give it a 7 out of 10.
