Heat a frying pan on a low heat, add the cumin seeds and peanuts and stir to prevent them from burning. After a few minutes they will begin to turn a golden brown colour. Remove from the heat and crush coarsely using a pestle and mortar.
Mix all the ingredients together in a bowl, including the roasted cumin seeds and peanuts. Check the seasoning and adjust the salt, black pepper and sugar to taste. Garnish with freshly chopped mint and serve chilled.
Notes
If you prefer your dishes less spicy then deseed the chilli before chopping.
