Fish sauce
Fish sauce is a clear, salty seasoning made by maturing fish with salt and drawing off the liquid. The broad family includes distinct regional sauces rather than one interchangeable method.
Roasted tomatoes, shallots, garlic and chillies are pounded into a coarse Lao-style dip, then seasoned with fish sauce, optional lime and coriander.

Jeow, also written jaew, names a family of Lao dips rather than one standard sauce. Jeow mak len is the tomato member: roasted tomatoes and aromatics are pounded into a seasoned dip. Lao cook Saeng Douangdara describes serving it with sticky rice and grilled chicken, and her recipe combines padaek with fish sauce, then finishes with cilantro.
The measured formula here is its own development. It uses 250 g tomatoes, 70 g shallots, 20 g garlic, 15 g chillies, 25 g fish sauce, optional lime juice and coriander. Its weights are independent of Saeng's recipe, and its base uses fish sauce without padaek. It should be read as a modern adaptation in the style of jeow mak len, not as a transcription or a universal Lao household formula.
Roasting or grilling softens the tomatoes, shallots, garlic and chillies while leaving charred patches. Keep the garlic cloves in their skins for roasting, then peel them once they have softened. Remove any badly burnt skin; the aim is patches of char, not an entirely blackened relish.
Pound or pulse the vegetables only until they form a coarse mixture. A smooth purée loses the uneven texture associated with pounded jeow. Add the measured fish sauce, optional lime juice and chopped coriander after pounding. The supplied formula gives no cooking temperature or separate roasting time; the total preparation estimate is 25–35 minutes.
Fish sauce is the only fish seasoning in this measured base. Saeng's version also uses padaek, a Lao preserved fish sauce, alongside clear fish sauce, plus MSG and cilantro. That source-specific combination is useful context but is not part of this formula's fixed ingredient list. Adding padaek would make a different variation; follow the ready-to-eat product's label and reduce the fish sauce accordingly.
Tomato size and water content vary. Saeng notes that larger, juicier tomatoes release more liquid than cherry tomatoes and may need draining after roasting. This batch uses a stated weight of tomatoes but does not specify a variety. The optional lime adds another sour note; no measurement establishes a preservation effect.
Serve the dip with sticky rice or grilled food. The roasted base freezes better without fresh coriander; freeze it before adding the herb, then add fresh chopped leaves after thawing.
This development formula has not been kitchen-tested or assessed for storage. Cool it promptly, refrigerate it for short-term use, or freeze portions. The source archive's 48-hour refrigerated window is a planning convention, not a measured shelf life for jeow. Do not can it or keep it at room temperature. Fish sauce is a fish allergen; check its label for other ingredients and allergen information.
This is an original measured development formula. It borrows roasted-aromatic and pounded-texture cues from a documented Lao jeow mak len recipe, while setting independent ingredient weights and using fish sauce rather than padaek in its base.
