Can I make this sauce ahead?
Yes. Prepare the sauce up to 2 days in advance, then reheat gently while cooking fresh noodles. The flavors deepen overnight.
What if I don't have somen noodles?
Use ramen, thin egg noodles, or vermicelli. Somen cooks fastest (2–3 minutes), but any thin noodle works with adjusted cooking time.
How spicy is this dish?
This base recipe is savory with mild heat. Add chili oil, Sichuan peppercorns, or chili flakes to your bowl for more spice.
Can I use tofu in this recipe?
Absolutely. Dice firm tofu and add it to the sauce in the last 2 minutes to warm through without breaking apart.
Is fish sauce essential?
Fish sauce adds umami depth, but you can reduce it to 0.5 tbsp or omit it. Increase soy sauce by 1 tbsp to compensate.
