Gamja Jorim (Soy-Braised Potatoes)
Cubed potatoes braised down in a sweet-savory soy sauce — a classic Korean side. Glossy on the outside, fluffy within, and just salty-sweet enough to make a bowl of rice disappear. Shishito peppers add color and aroma.

Heat the oil in a pan and stir-fry the potatoes over medium heat until the edges turn slightly translucent.
- ⏲ 10 min
Add 1 cup water with the soy sauce, sugar, and garlic, cover, and simmer until the potatoes are tender.
- ⏲ 4 min
When the liquid has reduced by half, add the peppers and keep simmering until the sauce is scant and glossy.

Tips & Variations
Variations
- Baby potatoes (al-gamja): Braise whole small potatoes with the skin on.
- Plain: Skip the peppers for a clean potato-only version.
- Spicy: Add gochugaru or a hot green chili.
- With beef: Stir in ground beef for a heartier braise.
Tips
- Soaking off the starch keeps the potatoes from sticking and the sauce clear.
- Stir-frying first seals the surface so they hold their shape and turn glossy.
- Add the corn syrup at the end for a shiny glaze — added early, it slows cooking.
- Do not stir too often while braising or the potatoes fall apart.
The basics behind this dish
- Blanching: Keeping Vegetables GreenBlanched vegetables go dull because of acid and heat. Why the pot should be large, why the lid stays off, and what the ice bath is really for.
- Salt: When You Add It Matters More Than How MuchThe same amount of salt either draws water out or seasons all the way through, depending on when it goes in. Osmosis, seasoning in layers, and why salt types are not interchangeable by volume.
- Knife Skills: Grip, Cuts, and Why Size MattersHow you hold the knife matters more than how fast you cut. The pinch grip, the claw hand, and why uniform size is a cooking decision rather than a cosmetic one.
