Step 1

First peel the onion and dice it finely.

Step 2

If you have time soak diced onion in a bowl of cold water with ice.

Step 3

Meanwhile, mix tomato puree/tomato ketchup, chilli powder and cumin powder together in a bowl. Add lemon juice.

Step 4

Drain the onions after 15 mins and ensure you pat dry with a clean kitchen towel to remove the excess moisture.

Step 5

Mix the onions in the tomato mixture and add salt to taste. Note that ketchup is usually salty so you may not need to add it.

Step 6

You can now keep this cold onion chutney in the fridge until serving time.
