For the bacon curry potato soup, cut the bacon into 1 cm cubes, render, add onions and roast until golden brown. Peel the potatoes, cut into 2 cm cubes and add to the roasted onions.
Pour in soup, season and simmer for about 20 minutes. When the potatoes are soft, sprinkle with chives and chervil and serve with a dollop of crème fraiche or whipped cream.
