Schools in NYC with pastry programs
Since I have gone to only one of these schools, and there not for pastry alone, I cannot vouch for any of these programs. But at least she could start here:French Culinary InstituteKump's Sorry, Kyle, if you see this, don't tell Linda I still called it this!The New SchoolNY Restaurant School
I'm assuming that she's looking for a career program. If she wants a recreational program, she shouldn't bother checking NYRS; they only have career courses. But then she could look into the "De Gustibus" courses at Macy's.
Hope this helps, at least wrt NYC. Actually, there may be more than this, but these are the biggies.
