Wok-tossed eggplant and pork, a fiery embrace of garlic and chili, rounded by basil's fresh whisper.
A home-cooked stir-fry from across Khmer households, rooted in the wok techniques absorbed from Teochew and Hokkien immigrants in the 19th century. The fish sauce-palm sugar base is purely Khmer — Chinese cooks would use soy and white sugar. "Cha" means stir-fry; "trop" means eggplant. The dish has no famous origin story because every cook in Cambodia has a version.
Home-cook stir-fry shaped by the Teochew-Hokkien wok tradition, but with fish-sauce-and-palm-sugar base instead of soy. Cha = stir-fry, trop = eggplant. Cut-side pre-sear before the wok-toss is the move; salt-soak first to pull bitter water.
Long Asian eggplant, halved and seared until the cut side blisters, then wok-tossed with ground pork, fish sauce, palm sugar, plenty of garlic, and bird's-eye chili. Thai basil goes in at the end and wilts on contact. Eggplant should be silky-creamy inside but still hold its shape; if it's gone to mush, the wok wasn't hot enough at the start.
Eggplant gets pre-seared cut-side down before the wok-toss — this caramelizes the flesh and seals it so subsequent stir-frying doesn't waterlog it. Salt-soaking the cut eggplant for 15 minutes pulls bitter water out beforehand. The biggest home-cook mistake is crowding the wok: eggplant in batches, not all at once, or the pan temperature crashes and you stew instead of fry.
Variations
Phnom Penh home version (ground pork, plenty of garlic); Battambang adds prahok for funk; coastal Kampot uses dried shrimp instead of pork; vegan Siem Reap versions use fermented black beans and pressed tofu.

Ingredients
How it's made
5 steps · 30 min
- 14 min
Slice eggplant and pork into bite-sized pieces.
Watch outSalt the cut eggplant and let it sit about 15 minutes, then blot — the beads of dark water it sweats out are the bitterness leaving.
- 28 min
Heat oil in a wok and fry garlic until golden.
- 38 min
Add pork and stir-fry until just cooked.
- 45 min
Toss in eggplant, bird's eye chili, and a splash of fish sauce.
Watch outSear the eggplant in batches with room in the wok; crowd it and the pan temperature crashes, so it stews and waterlogs instead of taking on color.
- 53 min
Finish with soy sauce, sugar, and fresh basil, stir until fragrant.
Watch outAdd the basil right at the end and toss just until you smell it — a few seconds; cook it longer and the fresh top-note goes flat.
