What are common mistakes when making Vietnamese bún and noodle assembly?

Question

Accepted Answer

Serving noodles hot — bún dishes use room-temperature noodles (except bún bò Huế which is a hot soup). Chopping the herbs — they're served whole on a shared herb plate. Not making nước chấm from scratch — bottled versions are one-dimensional. Skipping the pickled vegetables (đồ chua) — the acid is essential for balance. Dressing the entire bowl with sauce at once — each bite should be dipped or lightly sauced.
