Questions

Can I make Kongguksu gluten-free?

Yes. The gluten in this entry is 1 tbsp soy sauce, 4 oz dried soba or wheat noodles, cooked and cooled. Swap the soy-based sauce for tamari or coconut aminos; the pasta for a gluten-free one, cooked a minute short of its package time. Everything else proceeds as written.

How long does Kongguksu keep?

Refrigerate it in a sealed container for up to four days and stir it back together before serving.

Can I halve or double Kongguksu?

Yes. As written it serves 2. Every ingredient in this entry carries precomputed half and double quantities, and the app's batch dial rewrites them inside each step. Doubled, blend in batches rather than overfilling the jar.
