Vegetarian bun rieu
In Hanoi, bún riêu is a mid-morning bowl bought from street sellers who set up on low plastic stools: a tangy red tomato broth with rice vermicelli and soft, floating curds that are normally made from pounded paddy crab. Vegetarian cooks and Buddhist temple kitchens make bún riêu chay instead, folding crumbled tofu, egg and chopped shiitake into the same loose, spongy curds, and seasoning the broth with fermented tofu rather than shrimp paste. It arrives with fried tofu, lime, chilli, shredded water spinach and perilla, so each spoonful is sour, savoury and fresh at once. Chef's tip: let the tomatoes fry in the annatto oil until they collapse into a jammy paste before any stock goes in; that is where the broth gets its colour and depth.
