Korean Grandma's Korean Fried Chicken 🇰🇷👵

In this exploration of homestyle Korean culinary heritage, creator Danny Kim highlights the time-honoured techniques behind authentic Korean fried chicken, guided by the intuitive wisdom of a traditional Korean grandmother. For development chefs and kitchen teams aiming to refine their casual dining menu, this traditional approach offers invaluable lessons in texture management, fat rendering, and sauce adherence.

The Secret to the Ultimate Shatter-Crisp Batter

The primary technical lesson lies in the starch-to-moisture ratio. Unlike Western-style fried chicken, which often relies on seasoned wheat flour and buttermilk coatings, the traditional Korean method champions potato starch. This alternative starch source creates a remarkably thin, brittle, glass-like crust that naturally resists sogginess, even when tossed in rich, moisture-heavy sauces.

The preparation begins with a light marinade to season the meat, followed by a meticulous dredging process. The starch must be worked directly into the chicken's natural moisture to form a tight, paste-like barrier. This crucial step ensures that the coating adheres flawlessly to the protein, preventing the batter from detaching or ballooning during the frying process.

Mastering the Double-Fry and Glazing Technique

The defining hallmark of Korean fried chicken is the double-fry technique. Chefs must execute two distinct frying stages to achieve the desired texture. The initial fry is carried out at a moderate temperature to cook the chicken through, rendering out subcutaneous fat and initiating the exterior drying process. Following a brief resting phase—which allows residual steam to escape and surface moisture to dry—the chicken undergoes a rapid, high-temperature flash fry. This second plunge instantly vapourises surface moisture, resulting in the iconic "shatter" crunch.

Post-fry, the glazing technique is critical. The traditional glaze—a reduction of gochujang, soy sauce, garlic, and sweetener—must be cooked to a sticky, syrupy state. Rather than pool-coating, the hot chicken must be tossed vigorously in a hot wok or bowl with just enough glaze to micro-coat each piece. This thin lacquering maintains the structural integrity of the starch crust while delivering a punch of balanced flavour.
