Frequently Asked Questions
Q: How should I store opened packs of these noodles?
A: Once the outer packaging is opened, transfer any unused bundles into an airtight container. Keep them in a cool, dry cupboard away from moisture and strong odors. Under these conditions, the noodles will stay fresh for up to six months without textural change. Do not refrigerate opened dry noodles as the fluctuating humidity can cause condensation and microbial issues. If you live in a very humid climate, adding a food-grade silica gel packet to the container helps maintain crispness.
Q: Can I use these noodles for cold dishes like japchae-style salads?
A: They work wonderfully in cold applications. In fact, after boiling and rinsing with cold water, you can toss them with sesame oil and let them chill further. Because the noodles are starch-based, they remain flexible even when cold and do not harden like wheat pasta. For a vibrant salad, add julienned carrots, spinach, and a light soy-ginger dressing. The natural chewiness becomes even more pronounced when chilled, offering a refreshing bite.
Q: What is the difference between these bundled noodles and regular sweet potato starch noodles?
A: The inclusion of yam flour is the key point. Plain sweet potato noodles can sometimes turn too soft or pasty if overcooked. The yam component adds a firmer structure and a hint of purple hue, plus it enriches the fiber content. The bundled format also ensures portioning and prevents the nest of tangled strands often found with loose-pack noodles. Tongyou’s specific starch ratio has been refined over decades to balance elasticity and tenderness.
Q: Do I need to soak the noodles before cooking?
A: Pre-soaking is optional but can reduce boiling time. If you choose to soak, submerge a bundle in cold water for 10–15 minutes until it becomes pliable. Drain and then add to boiling water for 3–4 minutes. For those who forget to soak, direct boiling for 5–6 minutes works just as well. However, do not soak for longer than 30 minutes as the outer surface might begin to lose structural integrity and become gummy.
Q: How does Tongyou ensure consistent quality from batch to batch?
A: Tongyou operates a vertically integrated supply chain. The team tests raw sweet potato and yam flours for viscosity and amylose content before production. During extrusion, dough moisture is measured every 15 minutes, and the drying tunnel temperature is strictly segmented into three zones to prevent case hardening. Finished bundles go through a metal detector and a visual sorting system that rejects any bundle deviating from standard weight or appearance. Each lot is sampled and cooked in a test kitchen to validate sensory attributes.
Q: Are these noodles compatible with Instant Pot or pressure cooking?
A: We recommend traditional stove-top boiling for best results because high-pressure steam environments can cause rapid, uneven hydration that may turn the noodles mushy. If you must use a pressure cooker, add the bundle after the pressure cycle and use the sauté function with adequate water to simmer for 4–5 minutes with the lid off, giving you control over the texture.
