Cold sauces & condiments
Ngapi yay
ငါးပိရည် · A thin, pungent, savory Burmese condiment made by boiling fermented fish paste (ngapi) with water until the paste dissolves into an umami-rich liquid, then finished with raw aromatics — garlic, bird's eye chili, and lime juice. It functions as a reusable seasoning base and dipping sauce, the everyday table condiment of Lower Burma.
The formula
1 part ngapi : ~120 parts water (2 tbsp ngapi to 240 ml water)
Paste-to-water ratio of approximately 1:120 by volume; acid and aromatics added off-heat to preserve brightness.
Identity
- Foundational Burmese cold condiment and seasoning base
- Lower Burma (Bago, Yangon, Irrawaddy delta) everyday table sauce
- Built from fermented whole fish paste (ngapi), not a finished dish on its own
- Balances fermented-salty, sour, pungent, and hot flavor pillars
- Traditionally served as a communal dip for raw and blanched vegetables with rice
Ingredients
| Base | Fermented fish paste (ngapi, whole small freshwater fish) | The defining umami backbone; traditionally made from butter catfish, swamp barb, or snakehead murrel. |
| Liquid | Water | 240 ml per 2 tbsp ngapi; dissolves the fermented paste into a thin dipping broth. |
| Aromatics | Small onion, roughly chopped | Simmered with the base for sweetness and body. |
| Aromatics | Small tomato, roughly chopped | Simmered with the base; adds subtle sweetness and color. |
| Aromatics | Garlic cloves (whole + minced) | Whole cloves simmer with the base; minced cloves added raw at the end for sharp pungency. |
| Flavor | Fresh bird's eye chilies, finely sliced | Added raw off-heat; supplies the characteristic fresh heat. |
| Acid | Fresh lime juice | 1 tbsp; added off-heat to lift and balance the fermented saltiness. |
| Seasoning | Dried shrimp powder (optional) and salt | Optional umami booster and final salt adjustment. |
Method
- 1Combine ngapi with water (and whole garlic, onion, tomato if used) in a saucepan and bring to a boil.Heat and agitation are required to dissolve the dense fermented fish paste into a thin, homogeneous liquid.
- 2Reduce heat and simmer briefly, mashing any remaining solids against the side of the pan.Fully extracts the soluble proteins and salts while mellowing the harshest fermentation notes.
- 3Strain the liquid through a fine sieve, pressing to extract maximum flavor.Produces the characteristic thin, clear dipping broth and removes fish bones and insoluble matter.
- 4Cool the broth to room temperature.Prevents the raw aromatics from cooking and losing their fresh pungency.
- 5Stir in minced raw garlic, sliced bird's eye chilies, and fresh lime juice.Raw finishing preserves the bright, sharp top notes that define the condiment and balance the fermented base.
- 6Adjust with salt and optional dried shrimp powder; taste for balance of salt, sour, and heat.Ngapi salinity varies by batch; final seasoning is essential to hit the savory-sour-pungent target.
Techniques that matter
Dissolution by boiling
Ngapi is a dense, fermented paste that requires heat and dilution to become a dip rather than a spread.
Straining
Removes bones, scales, and insoluble fish solids to yield a clean, pourable broth.
Raw finishing
Garlic, chili, and lime are added off-heat so their volatile aromatics remain sharp and bright.
Variations & derivatives

Full table version with raw garlic, chili, lime, onion, and tomato; served with raw and blanched vegetables.
Ngapi ye (hot anchovy sauce)Burmese diaspora, fiery condiment style

Used in these dishes
Substitutions
- Burmese ngapi (fermented fish paste) → Thai shrimp paste (kapi) — Similar fermented umami profile; will taste slightly different and may need extra salt.
- Burmese ngapi → Canned anchovies mashed into water — Last-resort substitute; loses the deep fermented character.changes result
- Bird's eye chilies → Thai prik kee noo or serrano — Comparable fresh heat; serrano is milder.
Troubleshooting
Dip tastes overwhelmingly salty or fishy
Ngapi batch is heavily fermented or ratio skewed heavy on paste → Dilute with additional warm water and re-balance with more lime juice.
Cloudy, gritty texture
Insufficient straining or paste not fully dissolved → Re-strain through a finer mesh and mash solids more thoroughly during simmering.
Flat or muddy flavor with no bright top notes
Raw garlic, chili, or lime added too early or omitted → Stir in fresh minced garlic, sliced chili, and lime juice just before serving.
Off, overly pungent sourness
Fermented paste overcooked or stored too long warm → Discard and start with a fresh batch; never simmer ngapi yay for extended periods.
