Method

  1. In a non-metal dish, mix 500 g caster sugar, 500 g sea salt, 12 g lemon zest, 5 g lime zest and 200 g kashmiri chilli powder (the marinade chilli) until evenly combined.
  2. Rub 420–560 g sea trout fillet with spiced gin to taste. Lay the fillets flesh side down in the cure.
  3. Cover the dish and chill for 8 hours.
  4. Turn the fillets over, cover again and chill for another 8 hours.
  5. Rinse the fillets under cold running water until the cure is gone. Dry them with kitchen paper; the flesh should feel firm and have lost most of its moisture.
  6. Spread 200 g kasundi mustard over the flesh side of the fillets. Cover and chill until needed.
  7. Put 300 g kohlrabi, peeled and diced, into 398 g pickling liquor. Leave at room temperature for 1–2 hours, then chill until needed.
  8. For the pea purée, process 450 g petit pois, 12 g garlic, fresh ginger to taste, 18 g green chilli and 91.3 g mustard oil until completely smooth.
  9. Add caster sugar and sea salt to the pea purée to taste. Cover and chill.
  10. To serve, cut the trout into thin slices. Plate with the pickled kohlrabi and a little pea purée.

Sea trout fillet
  • Salmon fillet

    Use the same weight; add 1–2 minutes, as salmon is usually thicker.

  • Trout

    Use the same weight; cook 1–2 minutes less if the fillet is thin.

  • Firm white fish fillet

    Use the same weight; reduce cooking by 2–3 minutes and handle gently.

Spiced gin
  • Gin

    Use the same weight; for 100 g gin, steep a pinch of ground clove and ground cinnamon for 10 minutes, then strain.

  • Premium gin

    Use the same weight; it is smoother, so add the same spice pinch and taste before adding more.

  • Vodka

    Use the same weight; it is neutral, so steep with ground clove and ground cinnamon to mimic the spiced note.

Kasundi mustard
  • Wholegrain mustard

    Use the same weight, mashed smooth with a little lime juice; keeps mustard tang but lacks Bengali fermentation.

  • English mustard

    Use one-third of the weight, mixed with lime juice or water; much hotter, so taste as you go.

  • Mustard powder

    Use half the weight, mixed to a paste with water and a squeeze of lime juice; add late so the heat does not fade.

Caster sugar
  • Granulated sugar

    Use the same weight. It is slightly coarser, so stir a little longer to dissolve; in baking, grind briefly if a fine texture matters.

  • Demerara sugar

    Use the same weight, but dissolve it earlier as it is coarser. It adds a light caramel note and a little colour.

  • Ground jaggery or soft brown sugar

    Use the same weight; crush or grate jaggery first. It darkens the dish and adds molasses flavour, so reduce other liquid slightly.

Lemon rind
  • Lime

    Use the same weight of finely grated lime zest; sharper and more aromatic.

  • Orange

    Use the same weight of finely grated orange zest; sweeter and less sharp, so reduce sugar if any.

  • Lemon

    Use the same weight of grated zest from a fresh lemon; take only the coloured part, not the white pith.

Lime zest
  • Lemon zest

    Use the same weight; it is less sharp and more floral, so add a little extra lime juice if the dish needs tang.

  • Kaffir lime leaf

    Use 1 leaf for 1 tsp lime zest in curries; bruise and simmer whole, then remove. It gives aroma but not acidity.

Kashmiri chilli powder
  • Dried kashmiri chilli

    Grind deseeded dried pods to an equal weight of powder; gives identical vivid red colour and gentle warmth.

  • Red chilli powder

    Use 25% of the weight mixed with sweet paprika for colour; straight red chilli powder is substantially hotter and will make the dish fiery.

  • Chilli powder

    Use one-third of the weight; the sauce will be less intensely red and notably sharper in heat.

Kohlrabi
  • Turnip

    Use the same weight, peeled and cubed; similar texture, slightly peppery.

  • Potato

    Use the same weight, peeled and cubed; milder and softer, so add 5 minutes later if you want it to hold shape.

  • White radish

    Use the same weight, peeled and cubed; cooks faster and is more watery, so add later and reduce the gravy.

Pickling liquor
  • White vinegar

    Use 70% of the weight, make up the rest with water, and add a little granulated sugar if the liquor was sweet. Sharper and thinner.

  • White wine vinegar

    Use at 70% of the weight with water. Milder and fruitier than pickling liquor.

  • Malt vinegar

    Use at 60% of the weight with water; stronger and maltier, so reduce any other vinegar in the dish.

Green pea
  • Pea

    Use 1:1 by weight; cook straight from fresh or frozen with identical timing and sweetness.

  • Chana dal

    Use 60% of the weight in dry dal; boil until tender yet firm before stirring in, lending a nuttier texture rather than sweet pop.

Garlic
  • Garlic paste

    Use equal weight. Fry gently in oil or ghee with the ginger; incorporates smoothly into curries without visible minced bits.

  • Garlic powder

    Use 15% to 20% of the weight (about 1 g for every 5 to 6 g fresh cloves). Whisk into sauces; gives a savoury, toasted garlic flavour without raw pungency.

  • Shallot

    Use 1.5 times the weight, very finely minced. Sauté until golden; provides savoury allium sweetness, though it lacks garlic's pungent sulphur bite.

Fresh ginger
  • Ginger paste

    Use equal weight. Sauté in hot fat until the raw allium smell disappears; slightly wetter, but provides identical warmth and pungency.

  • Ground ginger

    Use 20% to 25% of the weight (1 g for every 4 to 5 g fresh). Stir into the gravy; adds peppery heat and warmth, though it misses the crisp, zesty kick of raw root.

Green chilli
  • Chilli powder

    Use 10 to 15% of the weight (about 1/4 teaspoon per chilli); imparts dry pungent heat and reddens the dish without the grassy crunch.

  • Dried red chilli

    Use 1 dried pod per fresh green chilli; snap in half and temper in hot oil for a deeper, toastier heat.

Mustard oil
  • Peanut oil

    Use equal weight. It handles high-heat cooking well, but lacks the signature pungent, nasal heat of mustard oil.

  • Vegetable oil

    Use equal weight. Neutral in flavour, so your curry will lack the characteristic Bengali or North Indian pungent punch.
