Fresh grated coconut chutney with mustard seeds and green chilli — the Assamese plains condiment

Ingredients

Method

  1. About Assamese Coconut Chutney: The Brahmaputra valley grows coconuts abundantly in its lowland villages, and fresh grated coconut chutney is the everyday relish of Assamese plains households. Unlike the South Indian coconut chutney, the Assamese version uses mustard oil and mustard seeds tempering, giving it a distinctly different character.
  2. Use fresh coconut: Fresh grated coconut gives by far the best flavour. Crack open a coconut, prise out the white flesh and grate using a coconut grater, box grater or food processor. If fresh is unavailable, frozen grated coconut (thawed completely) works as a substitute. Avoid desiccated coconut — it produces a dry, unauthentic result.
  3. Measure the coconut: You need 1 cup loosely packed fresh grated coconut. Avoid packing it tightly into the cup — fluffy coconut blends more easily.
  4. Prepare the green chillies: Take 2 fresh green chillies. Roughly chop. Remove the seeds for a milder chutney; leave them in for the traditional sharp heat.
  5. Peel the garlic: Take 2 garlic cloves. Crush lightly with the flat of a knife — this loosens the skin so it slips off easily. Discard the skin.
  6. Load the blender carefully: Place the chillies, garlic and a pinch of salt at the bottom of the blender — these are the hardest ingredients and need to sit closest to the blades. Add the grated coconut on top.
  7. Add lemon juice and water: Squeeze the juice of half a lemon over the top. Add 2 tbsp cold water. Cold water keeps the chutney bright white; warm water can make it look dull.
  8. Blend in pulses: Pulse the blender 5-6 times to break things down, then run for 10 seconds. Stop and scrape the sides with a spatula. The mixture should look thick and slightly coarse — Assamese coconut chutney is traditionally a coarse paste, not the smooth South Indian style.
  9. Adjust consistency: If too thick to scoop, add 1 more tbsp water and pulse twice. The final texture should be like wet sand that holds its shape on a spoon.
  10. Transfer to a serving bowl: Spoon the chutney into a wide shallow bowl rather than a deep one — the tempering needs surface area to land on.
  11. Prepare the tempering ingredients: Have 1 tsp mustard seeds ready in a small bowl. Have 1 tbsp oil ready (mustard oil for the most authentic flavour, or neutral oil if mustard is too pungent for you).
  12. Heat the oil for tempering: Pour the oil into a small tempering pan or any small pan. Place over medium-high heat. If using mustard oil, heat until it just begins to smoke — about 30 seconds — to remove the raw bitter edge.
  13. Pop the mustard seeds: Reduce heat to medium. Add the mustard seeds. Within 5-10 seconds they will start popping vigorously and jumping in the pan — keep a lid handy or hold a small splatter screen over the pan. Wait until the popping slows down, about 20 seconds total.
  14. Pour over the chutney: Immediately pour the entire sizzling tempering directly over the top of the chutney in the bowl. The hot oil will hiss and fill the kitchen with the sharp aroma of mustard. Do not stir for 30 seconds — let the heat soak in.
  15. Mix and serve: Now stir the tempering through the chutney with a spoon. Taste and adjust salt or lemon. Serve immediately at room temperature alongside steamed rice, dal, fish curry or as part of an Assamese thali. Best eaten within 2 hours; the bright flavour fades after that.
