Recipe Tips and Tricks

• Add Soba Last → Buckwheat noodles overcook easily (last 5–10 min).
• Press Tofu → Removes excess water for better texture.
• Use White or Yellow Miso → Milder flavor; red is too strong.
• Double Ginger → Fresh + ground for layered warmth.
• Save Noodle Water → Use to adjust broth thickness.
• Garnish Fresh → Scallions, sesame, and chili oil make it sing.
