Japanese Kenchinjiru Buddhist Temple Soup and Shojin Broth Traditions

Ingredients

• For the kombu dashi
• 15 g kombu (dried kelp), wiped clean with a damp cloth
• 1.2 litres cold water
• 200 g firm tofu (momen-dofu), crumbled by hand into irregular pieces
• 150 g daikon (white radish), peeled, sliced into half-moons
• 100 g carrot, peeled, rangiri (diagonal irregular) cut
• 100 g gobo (burdock root), scrubbed, rangiri cut, held in cold water to prevent discolouration
• 100 g lotus root (renkon), peeled, sliced on the diagonal
• 100 g konnyaku, torn into irregular pieces by hand, blanched briefly to remove odour
• 2 tbsp sesame oil
• Seasoning
• 2 tbsp soy sauce, light-handed — add gradually and taste
• 1 tsp salt, or to taste

Method

1. 1
   Place the kombu in 1.2 litres of cold water and bring slowly to just below a simmer over medium-low heat. Remove the kombu before the water reaches a full boil — extracting it at this point preserves the clean, marine sweetness of the dashi without introducing bitterness. The finished dashi should be pale gold and faintly fragrant of the sea. Reserve warm.
2. 2
   Crumble the firm tofu by hand into rough, uneven pieces. The irregular surfaces will absorb sesame oil and produce more browned area than cut slices. Heat 1 tablespoon of sesame oil in a wide, heavy pot over medium-high heat. Add the crumbled tofu in a single layer and stir-fry without excessive movement until the pieces are lightly golden and carry the faint, nutty smell of Maillard browning. Remove and set aside.
3. 3
   This step is where the dish lives or dies. Add the remaining sesame oil to the same pot. Add the drained gobo first — it requires the longest time to develop its characteristic deep, earthy, toasted aroma — then the carrot, daikon, lotus root, and konnyaku in succession, stir-frying each until the cut surfaces show colour and the pot is fragrant with the compound aromas of burdock and sesame. Do not crowd the pot; if necessary, work in two batches. A pale, unbrowned pot at this stage cannot be corrected by subsequent simmering.
4. 4
   Return the browned tofu to the pot with the vegetables. Pour over the warm kombu dashi. Bring to a gentle simmer and cook until the root vegetables — particularly the gobo and daikon — are fully tender when pierced with a skewer and offer no resistance at their thickest point.
5. 5
   Season with soy sauce and salt, adding each gradually and tasting between additions. Kenchinjiru is restrained in seasoning; the broth should be light, clean, and savoury rather than deeply coloured or salt-forward. The finished soup should be clear, with a pale amber tint from the soy sauce; opacity or a dark colour signals over-seasoning.
6. 6
   Ladle immediately into warmed bowls, distributing the vegetables evenly. The broth must be piping hot at the moment of service — the contrast between the clear, steaming broth and the substantial root vegetable mass is intrinsic to the dish. Serve without delay.
