Soy-Braised PotatoesGamja Jorim

Gamja jorim is a side dish that appears in Korean lunchboxes, on dinner tables with rice, and in meal prep containers on Sundays. It's sweet, savory, slightly sticky, and works cold or room temperature — properties that make it one of the more practical items in the Korean banchan repertoire.

I learned to make it when I was living in Sydney and cooking Korean food regularly for myself. The technique is jorim — braising in a sauce that reduces down to a glaze. It applies to all sorts of proteins and vegetables in Korean cooking; potatoes just happen to be the most forgiving version to learn.

What I got wrong initially was the sauce reduction. I added too much water and then covered the pan, which trapped the steam and left me with potatoes in a watery soy broth rather than potatoes with a sticky glaze. The recipe is clear: cook uncovered for fifteen minutes, stirring occasionally. The uncovered pan lets the liquid evaporate and concentrate. The corn syrup adds viscosity that pure sugar doesn't — it's what gives the final glaze its sheen.

The tip in the recipe is accurate: if the sauce dries out before the potatoes are fully cooked, add a small splash of water and continue. Don't panic. Jorim is forgiving in that direction. What's harder to fix is too much liquid at the end — you just have to keep cooking.

My Italian neighbor Giulia tried the leftovers I'd left in the fridge and texted me asking what those sweet-savory potato cubes were. She'd eaten them cold straight from the container. I told her that was the intended use case.
