# Expert Hacks:

01 -
  • Ready in under 30 minutes but tastes like it simmered all afternoon
  • The noodles develop this incredible slippery texture that absorbs every drop of flavor
  • Customizable with whatever vegetables are wilting in your crisper drawer
02 -
  • Harusame noodles continue softening in hot broth, so slightly undercooking them in the soaking stage prevents mushiness
  • Adding the spinach last preserves its bright green color and fresh texture
  • The broth tastes better if you let it cool slightly before serving, around 5 minutes off the heat
03 -
  • A few drops of chili oil or a pinch of shichimi togarashi transforms this into something completely different
  • Substitute shredded cooked chicken for tofu if you want more protein and a different texture profile
