Peel and finely chop the onion. Fry in hot oil in a pot until translucent. Dust with flour and curry and let it sweat briefly. Add stock and cream while stirring and bring to the boil briefly.
Leave to swell for about 10 minutes at medium heat. Season to taste with salt and pepper. Roast the flaked almonds in a pan without fat. Pluck the parsley leaves from the stalks, wash and pat dry.
Serve the soup garnished with flaked almonds and parsley.
