Notes & Annotations

Nōshō (濃醤) literally means 'thick/rich soy.' This likely refers to a tamari-like concentrated soy preparation, predating modern commercial soy sauce varieties.

English Recipe

Ingredients

  • silken tofu 豆腐 1 block (350 g)
    一丁 Chilled
  • soy sauce 醤油 200 ml
    For reduction

Method

Serves 2–3

1. Pour 200 ml soy sauce into a pot.
2. Bring to a gentle boil and simmer uncovered for 20–30 minutes, stirring occasionally.
3. As it reduces, it will become darker and more viscous — like honey or light caramel. When it reaches about 50 ml (a reduction of about 75%), remove from heat.
4. Let cool slightly. The sauce will thicken further as it cools.
5. Gently place a block of chilled silken tofu in a shallow serving bowl.
6. Pour or brush the thick, glossy soy reduction generously over the tofu.
7. Serve at room temperature or chilled, with a garnish of grated ginger or a whisper of yuzu if desired.

Nōshō means 'rich' or 'thick soy.' This concentration intensifies the savory umami and adds a subtle sweetness from the slow cooking. It is sophisticated and minimalist — no other seasoning needed.
