Avial — Kerala Mixed Vegetable in Coconut-Yoghurt (അവിയൽ)

Ingredients

• 150 g yam (elephant foot yam / suran), peeled, cut into 5–6 cm batons
• 1 medium raw banana, peeled, cut into 5–6 cm batons
• 3–4 pods drumstick (moringa), cut into 5–6 cm lengths
• 150 g ash gourd, peeled, cut into 5–6 cm batons
• 150 g snake gourd, cut into 5–6 cm batons
• 100 g green beans, topped, tailed, cut into 5–6 cm lengths
• 1 medium carrot, peeled, cut into 5–6 cm batons
• 1 small raw mango, peeled, cut into 5–6 cm batons; omit if unavailable
• For the coconut paste
• 150 g fresh coconut, grated
• 1 tsp cumin seeds
• 3–4 green chillies, roughly chopped
• 150 ml yoghurt (moru), thickened to near-hung curd consistency
• To finish
• 2 tbsp virgin cold-pressed Kerala coconut oil
• 2 sprigs fresh curry leaves
• to taste salt

Method

1. 1
   Grind the fresh grated coconut, cumin seeds and green chillies to a coarse, cohesive paste without adding water, so the coconut's own fat binds the mixture and the finished avial coats the vegetables rather than pooling beneath them. The paste should hold together and be pale, fragrant, and visibly moist from the coconut's own fat — not dry or crumbled.
2. 2
   Place the yam and drumstick pieces in a wide, heavy pan in a single layer, season with salt, cover tightly and set over a medium flame — the lid must stay on, because these two vegetables need the full trapped steam to soften without any added water diluting their flavour. Cook for 8–10 minutes until the yam begins to yield at its edges and the drumstick skins start to blister faintly.
3. 3
   Add the raw banana, carrot, snake gourd and raw mango, re-cover immediately so the accumulated steam is not wasted, and continue cooking for a further 5 minutes. Listen to the pan: a steady hiss means sufficient moisture remains, but a falling-silent pan signals that moisture is exhausted and burning is imminent.
4. 4
   Add the ash gourd and green beans and cook uncovered for a final 5 minutes, stirring gently once or twice — the lid comes off now so that any surplus liquid evaporates and the vegetables finish rather than stew. This is where the dish lives or dies: every vegetable must reach the same point of doneness simultaneously, yielding to a thumbnail's pressure yet retaining their shape and colour entirely, because overcooking collapses their structure and releases water that turns the avial soupy, while undercooking leaves the yam and drumstick hard at the centre.
5. 5
   Reduce the flame to its lowest setting and fold in the coconut paste, distributing it evenly over the vegetables so it warms through gently rather than frying, which would turn it oily and coarse. After 1 minute, add the thickened yoghurt and fold again, cooking for no more than 2–3 minutes in total from the moment the coconut paste enters the pan — the mixture should smell of warm fresh coconut, not of fried or oily coconut.
6. 6
   Remove from the heat, drizzle the virgin cold-pressed Kerala coconut oil over the surface and scatter the fresh curry leaves across the top without stirring, so the residual heat draws the fragrance up through the oil rather than driving it off. The dish is ready when that combined fresh-coconut-and-leaf scent rises clearly from the pan.
