Clean and wash the cauliflower and cut the florets from the stalk. Heat 1 tablespoon of oil in a wide saucepan, add the florets and fry briefly. Sprinkle with 1 tsp. sugar, dust with cumin and curry, sauté briefly.
Deglaze with broth and lime juice, bring to the boil, cover and cook for 15-18 minutes.
Wash the fish and pat dry, cut into cubes. Lift approx. 1/4 of the cauliflower florets out of the stock with a skimmer, drain well, set aside. Stir yoghurt and starch until smooth. Remove the pot from the heat, finely puree the contents.
Bring to the boil again, stir the mixed yoghurt into the soup. Bring to the boil and simmer for about 3 minutes. Then season to taste with salt, pepper and 1 pinch of sugar. Add the rest of the cauliflower florets back into the soup.
Meanwhile heat 2 tablespoons of oil in a pan, add fish and fry for 2-3 minutes while turning, season with salt and pepper, sprinkle with lime zest. Sprinkle soup with one teaspoon each of chutney, salmon and flaked almonds, arrange in soup bowls.
Possibly add mango chutney.
