Where to find a tart pan?  My first task in preparing for dinner on Tuesday has been a challenging one.  I've been to 3 retail stores and 1 restaurant supply store and am still tart-less.  Later today I'll up my ante and head to Williams & Sonoma where I will officially enter the world of the discriminating gourmet.   How could I even think of making the lemon meringe tart in a pie dish?!  What is a tart without the fluted golden brown crust? 

Also in search of a pastry bag and tips...
