I Understand Why One Sold Every 10 Seconds... Even the Spice-Sensitive Can't Resist [Tried and Tested]

From 100% Grade A Milk to Korean Dried Shrimp

Convenience store chain CU has launched a new product under its differentiated ramen brand, 'Cheat Key.' The Cheat Key series enhances familiar flavors by adding a "decisive twist," elevating the taste to a restaurant-quality experience.

Since its release on the 1st of last month, the Cheat Key series sold 200,000 units in just three weeks, and on the day of the promotional event, it even surpassed the daily sales of Shin Ramyun. Is this just the effect of a new product launch, or is it truly a ramen with a unique edge? As someone sensitive to spicy food, I tried both products myself.

The first one I tasted was the 'Cheat Key Real Cream Buldak Flavor' (2,200 won). Upon opening the lid, the first thing I saw was not the soup powder but a small pack of sterilized milk. Branded as 'Cheat Key Milk,' the pack bore the message, "100% Grade 1A raw milk." The contents included three items: the milk, a liquid sauce packet, and an additional powder packet.

The preparation method differed from that of typical cup noodles. After pouring in all the milk and adding a bit of water up to the line, you microwave it. Then, mixing in the liquid sauce and powder transforms the thin broth into a thick, creamy sauce almost instantly.

With the first bite, instead of the intense spiciness expected from buldak, a rich milky flavor came forward. The cream sauce delivers a savory, smooth taste that envelops the palate, with a subtle lingering heat that builds later. Whereas Samyang's Carbo Buldak Stir-fried Ramen wraps bold heat in cream, the Cheat Key version makes the cream the star. Even as someone who is not good with spicy foods, I could finish the bowl comfortably without reaching for water.

However, hardcore fans of spicy flavors might find it a bit mild. The portion size might also feel a bit small for adults, so pairing it with a triangle kimbap or a hot bar is recommended for a more satisfying meal.

The second was the 'Cheat Key Rich Shrimp Soup Noodles' (2,100 won). This variety uses both a powder and a finishing shrimp powder. While it can be prepared in a microwave, I followed the traditional method by pouring hot water and waiting four minutes. As soon as the lid was lifted, a pronounced shrimp aroma was immediately noticeable—deeper and more savory than Nongshim’s long-standing bestseller, the 'Big Bowl Shrimp Soup Noodles.'

Inspecting the toppings, I found a generous amount of domestic dried shrimp and thick pieces of kelp. With the first sip of broth, the unique umami of shrimp was clearly present. Rather than being sharply spicy, this ramen focused on delivering a refreshingly deep broth flavor.

Because part of the noodles are made with rice, their texture is softer and more delicate than typical fried noodles, breaking apart easily rather than being very chewy. While those who prefer extra-chewy noodles might have mixed feelings, the texture pairs well with the broth, making it an easy and enjoyable option.

The Cheat Key series demonstrates that convenience store-private label (PB) ramen is now competing with more than just low prices. With a preparation method that involves real milk and toppings made from domestic ingredients, elements not often found in regular cup noodles, CU is pushing for differentiation. If you prefer savory flavors to spicy ones, try the 'Real Cream Buldak Flavor.' On days when you crave a hearty, rich broth, the 'Rich Shrimp Soup Noodles' is a great option. At the very least, these products will dispel any notion that convenience store PB ramen is just ordinary.
