Chopped preserved radish — dried, salted daikon known as cai-pu — soaked, squeezed, and fried until fragrant, then stirred through beaten egg and pan-fried into a thick, browned omelette. Salty, savory, and faintly sweet, with a chewy bite running through the soft egg. A cornerstone of Taiwanese home cooking and old-school rechao menus.
Cai-pu is one of Taiwan's oldest preserves — daikon radish salted and sun-dried to survive humid summers without refrigeration, a thrift rooted in early farming and immigrant households. Folding it into eggs turned a cheap pantry staple into a quick, protein-rich dish, and cai-pu egg became a defining gu-zao-wei — 'old-time taste' — passed down at family tables across the island. Aged cai-pu (lao cai-pu), darkened and mellowed over years, is especially prized and gives the omelette its deepest flavor.
The egg is thick and just-set, browned and a little crisp at the edges, soft in the middle. Running through it are bits of cai-pu — chewy, salty, deeply savory, with the concentrated sweetness that long curing brings. Each forkful is tender egg against firm radish, plain enough to eat bowl after bowl of rice.
Two things make or break it. First the cai-pu: it is heavily salted, so it must be soaked and squeezed dry, then dry-fried to drive off water and concentrate its aroma before meeting the egg — wet radish would steam the omelette and make it weep. Second the egg: poured into hot, well-oiled pan, the proteins coagulate fast and the underside browns via the Maillard reaction, giving the prized crisp edge while the center stays soft. The fried radish is mixed in raw-egg stage so every bite carries it.
Variations
Sweet cai-pu (tian cai-pu) gives a rounder, less salty omelette; some add chopped scallion or a little chili. Aged lao cai-pu makes a darker, more intense version. A loose, custardy style stays soft throughout, while the night-market style is fried hard and crisp.

5 steps · 10 min
- 15 min
Rinse the preserved radish, soak it briefly to draw out excess salt, then squeeze it very dry and chop fine.
Watch outSoak and squeeze the salted radish very dry — wet radish steams the omelette and makes it weep instead of crisping.
- 23 min
Dry-fry the chopped radish in a little oil over medium heat until fragrant and slightly toasted; let it cool a moment.
Watch outDry-fry the radish until fragrant and lightly toasted — driving off the water first concentrates its aroma into the egg.
- 31 min
Beat the eggs, season lightly with white pepper, and stir in the fried radish (and chopped scallion if using).
- 41 min
Heat a generous film of oil in the pan until hot, pour in the egg mixture, and spread it into a thick round.
- 54 min
Fry undisturbed until the underside is browned and set, then flip and brown the second side. Slide out and serve.
Watch outFry undisturbed until the underside browns and sets — that crisp, Maillard-browned edge is the whole point.
