Silky rice noodle rolls filled with shrimp or pork are a fresh, light dim sum classic. A healthy option for a family brunch or breakfast spread.
Combine rice flour, tapioca starch, cornstarch, and water in a mixing bowl. Whisk until completely smooth and no lumps remain.
Add salt, sugar, and white pepper to the batter and let it rest for 10 minutes to hydrate starches and develop a silky texture.
While the batter rests, cut shrimp into bite-size pieces and toss with green onion and a touch of soy sauce.
Set up a steamer with a flat pan. Pour a thin layer of batter into the pan, cover, and steam on medium-high heat for 2–3 minutes until just set.
Quickly arrange shrimp pieces over the surface; steam 1 more minute until shrimp turn opaque.
Using a spatula, roll up the noodle sheet with shrimp inside while still warm and transfer to a plate.
Repeat steaming and rolling steps for remaining batter and filling, lightly brushing rolls with sesame oil after each batch.
Mix remaining soy sauce and a dash of sesame oil for drizzling over the rolls just before serving.
