Banana Stalk Curry (Kaeng Yuak / แกงหยวก)

Zero waste isn't a trend. It's how people in the northern highlands have always cooked.

Kaeng yuak uses the inner stalk of the banana plant. Not the fruit. Not the leaf. The trunk. After you harvest the bananas, a massive fibrous column stands in your yard doing nothing. A Central Thai cook would ignore it. A Lanna cook peels away the tough outer layers until she reaches a pale, tender core with a texture somewhere between heart of palm and a soft zucchini. She slices it, soaks it in lime water to stop it from browning, and drops it into a curry built on pork broth and a Lanna kreung tam.

Ajarn always said the kreung tam is everything, and in Lanna cooking the kreung tam tells you exactly where you are on the map. More ginger than galangal. Dried chilies that bring warmth, not violence. And tua nao (แผ่นถั่วเน่า), the fermented soybean disc, standing in for shrimp paste because the mountains are a long way from the sea. Tua nao gives you the same fermented depth as kapi but through a completely different pathway: soybean protein fermentation instead of shrimp. Same principle, different raw material. That's the system adapting to geography.

This curry has no coconut milk. Coconut palms don't grow in the northern highlands. The broth is water and pork bones, nothing more, and the flavor comes entirely from the paste and the slow simmer of pork ribs releasing collagen into the liquid. When you taste a bowl of kaeng yuak, you're tasting the mountain kitchen: herb-forward, gentle, built on what's growing within arm's reach of the house. Finish it with a fistful of phak chi lao (ผักชีลาว), the dill that shows up in almost every Lanna curry and signals to your mouth that you're eating Northern Thai, not Central. Sticky rice. Always sticky rice. Never jasmine. That's the law up here.
