GS Gonghwachun Jjajang is widely considered the "premium king" of instant black bean noodles. It is a private-label brand from GS25 (a major Korean convenience store chain) and is branded after Gonghwachun, the legendary restaurant in Incheon's Chinatown credited with inventing Jjajangmyeon.
Liquid Sauce vs. Powder: Unlike most Jjajang ramyun (like Chapagetti) that use a powder base, Gonghwachun uses a heavy, retorted liquid sauce. It contains actual chunks of stir-fried onions, potatoes, and meat, giving it a glossy, restaurant-quality finish.
Flavor Profile: It is deep, earthy, and savory with a slight smoky (wok-hei) sweetness. It lacks the "instant" chemical aftertaste often found in cheaper brands.
Noodle Quality: The noodles are thicker and flatter, designed to hold onto the heavy black bean sauce better than thin noodles.
