Equipment

Ingredients

  • 1 large onion approx. 180g, chopped
  • 1 tsp cumin seeds toasted
  • 3 tbsp tomato ketchup (I use Heinz)
  • 1 tbsp tomato purée
  • 1 tsp chilli powder (I use 0.5 tsp mild and 0.5 tsp hot)
  • a pinch of salt
  • 0.5 tsp lemon juice
  • 0.5 tsp rapeseed or sunflower oil

Instructions

  • Place the chopped onions in a medium mixing bowl with some ice cubes and cold water and put it in the fridge for an hour.
  • Meanwhile, toast the cumin seeds - heat a small frying pan over a high heat for 2 to 3 minutes. Add the cumin seeds in a single layer and toast for 1 minute, tossing constantly. Transfer the toasted cumin seeds to a plate so that they cool and stop cooking.
  • When the hour is up, drain the onions in a colander, remove any ice cubes and pat the onions dry with some kitchen roll.
  • Return the onions to the mixing bowl and mix in the toasted cumin seeds, ketchup, tomato purée, chilli powders, salt, lemon juice and oil with the cold onions.
  • Transfer the onions to a serving bowl and place them in the fridge for at least 45 minutes before serving.
  • Enjoy with poppadoms and mango chutney as a starter or as a side with a feast of your favourite Indian dishes.

Notes

  • Optional variations:
    • Minty spicy onions – add a tsp of dried mint or a tbsp of chopped fresh mint leaves for a minty version.
    • Extra hot spicy onions – try different heat levels with hot chilli powder, chilli flakes or chopped fresh red chillis.
  • This curry house spicy onions recipe is easily adapted if you’re cooking for less or more people.
