Northern Thai pig-brain parcels seasoned with chilli paste.

About Aep Ong-o
Chiang Mai University Library documents aep ong-o as a Lanna pig-brain preparation. Its recipe combines the brains with a pounded chilli paste, herbs and banana-leaf wrapping for the regional aep style.
Dried bird chilli, garlic, shallot, lemongrass, galangal and turmeric provide the paste’s aromatic seasoning. Shrimp paste and salt add savoury depth, with makrut lime leaves, coriander and spring onion throughout the mixture.
The filling sits inside folded rectangular leaf parcels. The source describes browned, crisp wrappers around the seasoned brain mixture, distinguishing the leaf exterior from the softer filling.
