Dried rice noodles are readily available, but homemade fresh noodles are a fun project. If you've ever made the light pastry dough known as pâte à choux (the base for gougères and profiteroles), the first step to making the noodle dough will be familiar. The flour and water are mixed together, then cooked on the stove top until thick (this step also cooks out the raw-flour taste).
This is a two-person operation: once the paste thickens, one person will need to hold the pot down while the other stirs continuously. You will need a potato ricer for extruding the spaghetti-like noodles. The flavor of these noodles improves if you let the initial rice flour-water mixture ferment at room temperature for four days. While not essential to the success of the recipes, it does lend a nice tanginess to the finished noodles. However, if you are in a rush, you can let it soak overnight. The noodles can be used in Bún Bò Hue or as the base for noodle bowls.
