Japanese Ishikari Nabe Hokkaido Salmon Hotpot and Regional Dairy Integration

Ingredients

• For the base broth
• 1 (split) Salmon head and collar, cleaned, split by the fishmonger
• 1 piece (10 cm) Kombu, wiped clean with a damp cloth
• 1.2 litres Cold water
• 600 g Hokkaido wild salmon or high-fat coho salmon fillet, skin on, cut into 5 cm pieces; bone-in collar pieces included where available
• 200 g Daikon, peeled, cut into 1 cm half-moons
• 300 g Hakusai (napa cabbage), cut into 5 cm pieces, white ribs separated from leafy tops
• 150 g Firm tofu (momen), cut into large cubes
• 100 g Konnyaku, torn into rough pieces by hand, blanched 1 minute
• 1 medium stalk Burdock root (gobō), scrubbed, shaved into thin diagonal slices, held in cold water
• For the miso finish
• 80 g White or awase miso, not red miso; dissolved in a ladleful of broth before adding
• For the dairy finish
• 25 g Cultured Hokkaido butter (Yotsuba or equivalent), added at the final minute
• 60 ml Heavy cream, optional; added with the butter for the richer variation
• Seasonal addition (optional)
• 1 ear Hokkaido corn (tōmorokoshi), cut into 3 cm rounds

Method

1. 1
   Place the split salmon head and collar in the donabe or a heavy pot with the kombu and 1.2 litres of cold water. Bring slowly to just below a simmer over medium heat. Remove the kombu before the water boils. Continue at a bare simmer for 20 minutes, skimming any grey foam that rises. The broth is ready when it has turned a pale gold and carries a clean, gelatinous weight on the spoon.
2. 2
   Remove and discard the spent salmon head, or reserve any picked meat for the table. Add the daikon, burdock, and konnyaku to the broth. Maintain a moderate simmer for 15–20 minutes. Test the daikon with a skewer: it should meet no resistance at the centre.
3. 3
   Add the white cabbage ribs, corn rounds if using, and tofu. Simmer a further 5 minutes. The ribs will have begun to turn translucent at their edges while retaining a slight bite.
4. 4
   In a small bowl, whisk the miso with a ladleful of the hot broth until fully dissolved. Reduce the heat so the pot is barely simmering — not boiling. Stir the dissolved miso into the pot. The broth will cloud slightly and carry the miso's aroma forward without sharpness. Do not allow it to boil again from this point. This is where the dish lives or dies: miso added to a hard boil, or boiled at length after addition, loses its aromatic character and becomes flat and over-salty.
5. 5
   Add the salmon fillet pieces, skin side down, and the leafy cabbage tops. Cover and cook at the gentlest simmer for 5–7 minutes only. The salmon is done when the flesh has shifted from translucent to a pale, opaque coral at its thickest point and yields easily to a chopstick without flaking apart entirely. Do not extend cooking.
6. 6
   Add the cultured butter and, if using, the heavy cream. Stir once, slowly, to incorporate. Taste the broth: it should read as round, savoury, and lightly rich — not sharp with salt. Adjust seasoning conservatively; the butter will intensify perceived saltiness. Serve immediately in the donabe, which retains heat for tableside eating.
