Soak poppy seed in water for 30 minutes. Then grind it into a smooth paste with very little water and a couple of green chillies if you like spicy food.
Then cut onions into fine slices.
Heat 2-3 tbsps of mustard oil and add nigella seeds and 2 green chillies. Add the onions to this and sweat the onions on medium to low heat. You have to caramelise the onions without browning them.
When the onions have become soft, add the poppy seed paste and continue cooking on medium heat.
Keep stirring and frying till oil starts to come out from the sides. Add salt and sugar and split green chillies.
Before taking it off the heat, drizzle 1 tbsp of mustard oil.
Serve with rice.
