Bring a saucepan of water to a full boil, lower the eggs in gently, and cook for exactly 7 minutes. Transfer immediately to cold water to halt cooking so the yolk stays dense and jammy rather than chalky through — the right texture to hold its shape in hot oil. When cool enough to handle, peel carefully, then pat each egg completely dry with kitchen paper, because any surface moisture will cause the oil to spit violently and prevent the skin from blistering properly.

Heat the oil in a wok to 180°C and lower the dried eggs in one at a time, working in batches if necessary so the oil temperature does not drop and turn the surface greasy rather than crisped. Fry for 3–4 minutes, turning carefully so all sides are exposed to the oil. The eggs are ready when the surface is golden-amber, blistered, and irregular — the smooth white of the boiled egg entirely replaced by a lacy, textured crust.

Combine the tamarind water, dissolved palm sugar, and fish sauce in a small pan over medium heat and cook, stirring, until the sauce reduces to a dark, glossy consistency that coats the back of a spoon and pours in a slow, steady stream — thick enough to pool at the base of the plate, thin enough to pour freely. This is where the dish lives or dies: reduced too far, the sugar crystallises on cooling and the sauce turns grainy; too thin, it runs off the egg and is absent from each bite.

Halve the fried eggs lengthways and arrange on serving plates, then pour the hot tamarind dressing directly over the eggs while it is still fluid so it seeps into the crevices of the blistered surface rather than setting on top in a solid film. Scatter the crispy fried shallots and dry-roasted chilli flakes over the top, finish with coriander leaves, and serve immediately. The correct result carries the full sensory range in a single bite: the blistered, slightly crisp exterior, the dense fried white, the dark sweet-sour sauce, and the crunch of the shallot.
