Nuoc cham — the Vietnamese dipping sauce of fish sauce, lime, sugar, garlic, and chilli — is the table condiment of Vietnam, present at virtually every meal. Unlike nam jim (which has dozens of specific calibrations for specific preparations), nuoc cham has a single target balance that functions as a universal condiment. The calibration: the four flavours must be balanced so that no single one dominates — neither assertively fishy (too much fish sauce), nor aggressively sour (too much lime), nor sweet, nor hot.
- **The dilution:** Nuoc cham uses diluted fish sauce — the full-strength sauce is diluted with water (1 part fish sauce to 3–4 parts water). This dilution is what makes nuoc cham a light condiment rather than a seasoning. - **The ratio:** Approximately equal parts fish sauce, lime juice, and water, with sugar to balance and chilli and garlic to flavour. [VERIFY] Alford and Duguid's specific ratio. - **The garlic:** Finely minced — present as tiny fragments, not as a paste. The garlic should flavour without dominating. - **Nuoc cham for banh mi:** Slightly sweeter, with julienned carrot and daikon pickled in rice vinegar — the carrot-daikon pickle is technically do chua, served alongside. - **Nuoc leo (peanut sauce):** For fresh spring rolls (goi cuon) — hoisin sauce base, diluted with water, garlic, chilli, topped with crushed peanuts.
