Tips
Use ice water or refrigerate noodles before serving for extra coldness.
Toast sesame seeds yourself for deeper flavor than pre-roasted.
Whisk sauce thoroughly to blend gochujang evenly.
Good to Know
Refrigerate leftovers in airtight container up to 2 days. Sauce and noodles separate best.
Make sauce up to 1 day ahead. Cook noodles and chill up to 4 hours ahead. Assemble just before serving to prevent sogginess.
Serve immediately after assembly while noodles are cold and vegetables are crisp. Accompany with extra gochujang or sriracha on the side.
Common Mistakes
Do not skip chilling noodles thoroughly to avoid warm, limp texture.
Do not add sauce until serving time to avoid soggy noodles.
Do not use room-temperature water for noodles to avoid losing the cold appeal.
