A cantankerous old French woman who owned a bakery in (of all places) Fremont, CA, ruined croissants and french pastries for me for most of my life. All breads and pastries after just couldn't compare. A few in Paris came close, but C'est Si Bon was still the standard by which I judged all croissants, tarts and pastries. Well, Ding-Dong the witch is dead. Olivier Potier has set the new standard to ruin everything that comes after.
