Make authentic kai look keuy (Thai son-in-law eggs) in about 20 minutes with golden fried eggs, sweet-sour tamarind sauce, crispy shallots, and chilies.
Boil and fry the eggs: Boil the eggs for 5–6 minutes for soft-boiled or 8–10 minutes for hard-boiled. Peel and pat dry, then fry in hot oil until golden brown. Drain well.
Fry the shallots and chilies: Fry the sliced shallots until golden and crispy. Remove and drain, then fry the dried chilies for about 10 seconds and set aside.
Make the tamarind sauce: Add water, tamarind paste, palm sugar, and fish sauce to a small pan. Cook over low to medium heat, stirring until the sugar has dissolved and the sauce is smooth and slightly thickened.
Assemble and serve: Slice the fried eggs in half and arrange on a plate. Spoon the tamarind sauce over the eggs and top with crispy shallots, fried chilies, and fresh coriander. Serve immediately.
