Did you know — Korean culture
Grilled eel is traditionally eaten in Korea as a stamina food during the hottest stretch of summer, the same logic behind samgyetang's boknal tradition — eel is unusually rich in protein and fat for a freshwater fish, which made it a practical, calorie-dense choice for getting through the most exhausting part of the year long before that idea had scientific backing.
Building the glaze up in several thin layers, rather than pouring on one thick coat, is what gives jangeo gui its deep, lacquered look and flavor. A single heavy coat burns before it has a chance to properly caramelize, while thin layers brushed on repeatedly build real depth without scorching.
Starting skin-side down and giving it the longest initial sear helps render some of the eel's natural fat and gets the skin properly crisp before the glaze goes anywhere near it — glazing too early leaves the skin soft instead of giving it that initial textural contrast.

Troubleshooting
Glaze burning before it caramelizes? A single thick coat was probably applied — brush on thin layers instead, building up the color and flavor gradually over a few passes.
Eel skin staying soft instead of crisp? Give it a longer initial sear skin-side down before any glaze goes on, so the skin has a chance to crisp on its own first.
Eel tasting fishy or off? Make sure it's genuinely fresh and properly cleaned before cooking — the marinade and glaze can't fully mask a subpar starting point.
