A wholesome, deeply comforting soup crafted from slow-simmered stock, aromatic garden vegetables, and fresh herbs, served with crusty bread.
Simmer the rice in the stock in a pot for 15 minutes until tender.
Whisk the yogurt, egg yolk, and flour until smooth, then whisk in a ladleful of the hot stock.
Pour the yogurt mixture into the pot in a steady stream, stirring constantly.
Cook over low heat for 10 minutes, stirring, without letting the soup boil.
Melt the butter, fry the mint in it for 30 seconds, drizzle over the soup, and serve.
