This recipe requires two 8-inch round nonstick cake pans and two 1-inch-tall metal cookie cutters of any shape. Be sure to use finely ground rice flour (not glutinous or sweet rice flour); do not use stone-ground or coarse rice flour, which will result in grainy noodles. Look for finely ground rice flour and potato starch (not potato flour) in well-stocked supermarkets or Asian markets or online.

Combine ¾ cup white rice flour and ¼ cup potato starch in medium bowl. Add 1 cup (8 ounces) water and stir well to form thin batter.

Add water to Dutch oven until it measures about ½ inch deep. Place two 1-inch-tall metal cookie cutters in center of pot.

While water comes to simmer, fold 18 by 6-inch piece of aluminum foil lengthwise to create 18 by 3-inch sling.

Lightly brush 8-inch round cake pan with oil. Stir batter to recombine, then add ⅓ cup to prepared pan, swirling pan gently until batter evenly covers bottom. Place pan in center of sling.

Grasping sling at both ends, lift pan up and place on top of cookie cutters. Tuck ends of sling inward, cover pot, and steam for 5 minutes, checking noodle sheet halfway through steaming to ensure that it has not puffed away from bottom of pan. (If noodle sheet has puffed, cook uncovered for about 15 seconds so that it deflates back to bottom of pan, then re-cover pot and continue steaming.)

Grasping sling at both ends, carefully lift pan from pot and place on wire rack. Slide sling from beneath pan. Brush top of noodle sheet with oil and let cool for 3 minutes.

Use your fingers to gently peel noodle sheet out of pan, then place sheet, oiled side down, on cutting board. Brush top side with oil.

Repeat steps 4, 5, and 6 three more times, using remaining batter and alternating pans, for 4 noodle sheets in total, stacking oiled noodle sheets on top of one another. Wipe pans clean in between batches and add additional water to pot as needed to maintain water level.

Brush blade of a sharp chef’s knife lightly with oil, then slice stacked noodle sheets into ¾-inch-wide strips. Carefully separate strips into individual noodles, place on a large plate (it is OK for noodles to rest on top of one another in a pile) and cover tightly with plastic wrap. Noodles can be prepared up to 2 hours in advance and held at room temperature.
