wide rice noodles in metro detroit
Hey Rheta, don't know how far afield you want to go, but the Saigon Market on John R in Madison Heights might be worth a look.
I know the Asian market by me on Southfield, the generically named Oriental Market (they have a smattering of everything, including Filipino and Jamaican food), has a large selection of rice noodles but not sure if they have them as wide as you like. Worth a stop if you ever make Penzey's runs.
If VTB's suggestion doesn't have them, I think you'll need to go to a Southeast Asian market, which unfortunately, seem clustered in the Madison Heights and Warren area. Here are two places that DEFINITELY have these noodles:
30925 Dequindre Rd
Madison Heights, MI 48071
21701 Hoover Rd
Warren, MI 48089
coneywitheverything's suggestion of Saigon Market would probably work too.
Even if it's a drive to get to Madison Heights/Warren, these stores will have all the fresh produce, spices, soy sauces, etc. that you need to make your dish... all for much lower prices than you'll pay at a place like Hiller's.
