Korean instant noodles are famous for their heat, but not all spicy ramen is created equal. We ranked six of the hottest options available in the UK from merely warm to genuinely painful.
The Scoville Scale of Korean Instant Noodles
Korean noodle brands compete aggressively on heat, and the results are some of the spiciest instant foods available anywhere. The Scoville ratings are not always published, but the Korean internet community has done extensive testing and ranking. What follows is our heat-ranked list from hottest to mildest, all readily available in the UK.
The Top Tier: Prepare Yourself
**Samyang Buldak 2x Spicy** sits at the peak. This is the double-strength version of the already-fierce Buldak Hot Chicken ramen, clocking in at around 10,000 Scoville units. The sauce is a concentrated capsaicin bomb that builds relentlessly. It is not a pleasant lunch — it is a challenge, and you need dairy nearby. Only attempt this if you have a proven tolerance for extreme heat.
**Samyang Buldak Original** is the one that started the global fire noodle challenge. At roughly 4,400 Scoville units, it is significantly more manageable than the 2x version but still very hot by any reasonable standard. The chicken flavour comes through underneath the heat, and the noodles themselves are thick and chewy. This is where most people's spice tolerance finds its limit.
The Middle Ground
**Paldo Teumsae** is an underrated contender — a soup-based ramen with a serious chilli hit that sneaks up on you. The broth is red, fragrant, and builds heat with each spoonful. **Samyang Buldak Stew Type** is the soup version of the Buldak range — it dilutes the heat into a broth, making it more bearable than the dry original while still packing considerable punch. Both are satisfying meals rather than endurance tests.
The Entry Level
**Nongshim Shin Ramyun** is the benchmark — the spicy ramen that most UK consumers encounter first. By Korean standards, it is medium heat. By British standards, it has a proper kick. The flavour is complex and beefy, and the heat is warming rather than painful. **Ottogi Yeul Ramen** is slightly hotter than Shin Ramyun, with a cleaner chilli flavour and less of the beef-stock background. It is underrated and deserves wider recognition.
Survival Tips
For any of the top-tier noodles, have cold milk or yoghurt on hand — water does nothing for capsaicin. Adding a slice of processed cheese to the broth (a genuine Korean technique) smooths out the heat. And cook an egg into any of these — the protein and fat help moderate the burn while making the meal more substantial.
