Begin by cutting the mangoes into small 1.5cm by 1.5cm cubes.
Place the mangoes in a large mixing bowl. Grate the zest of 1 lime into the mangoes.
Squeeze juice from half a lime into the mangoes. Add more lime juice to taste if required later.
Chop a bunch of coriander leaves (or use mint leaves if you hate the taste of coriander) into fine bits.
Add the chopped coriander to the mango mixture.
Stir well to combine. In fact, Suvarna recommended to stir well after the addition of every ingredient.
Cut the shallots or red onion into very thin slices.
Add the sliced shallots or red onion to the mango mixture and stir well to combine.
Add 1/2 teaspoon of salt or to taste.
Add 1/2 teaspoon of black pepper or to taste.
Add 1 teaspoon of sugar or to taste.
Stir well to combine and do a taste test. Add lime juice, sugar, salt or pepper as necessary to get a nice savoury sweet tangy flavour.
Finally add the chopped chillis. Add according to your own heat tolerance. Some chillis are more spicy than others so add a little at a time till you acquire the desired spiciness. Stir well to combine.
Cover the bowl with cling wrap and place bowl in the fridge for at least 1/2 hour for the flavours to combine.
Keep the mango salsa chilled till ready to serve.
