I have been using a Tramontina Triply DO (stainless/aluminum/stainless sandwich).  This is a fairly substantial construction but no where near cast iron thickness.  The lid is single layer stainless and the handles are solid stainless.  Plastic handles will suffer in a 450 to 500 oven. I always preheat the oven, but have tried both a hot and a cold start for the DO.   Both methods work very nicely with similar oven spring.  The cold start allows the dough to spread to the edges of the DO, producing a round, domed loaf with nice crust.  The hot start "freezes" the dough in "rustic" irregular shapes and the crust seems a bit crispier.  I adjust lid-off bake time to achieve 200-210F on an instant read thermometer.

Can I substitute a stainless steel pot for the traditional iron dutch oven?
I am an Indian citizen living in the US since 2008 with an F1 Visa. I am a resident for tax purposes. Can I claim exemption under the India US Tax Treaty (21) "Students and Business Apprentices From India"? So Do I have to file the 1040NR in spite for being a resident alien for tax purposes?

Could anyone site me IRS publications which clarifies this? I am looking through p519 and am lost :-/
