If you've ever ordered poppadoms at a curry house, you'll know the star of the show is often the spicy onions. It's how I judge a good Indian restaurant or takeaway...if I love their spicy onions, I'll definitely go back!
This simple, punchy onion salad is tangy, slightly sweet and packed with spice - and the good news is you can make it at home in just minutes using everyday ingredients.
Enjoy as a starter with poppadoms and mango chutney, onion bhajis, samosas and pakoras, or as a side dish with your favourite Indian curries. It's best eaten fresh, but will keep for a maximum of 2 days in fridge.
The original recipe is from The Curry Guy website.
