Japanese Hell Ramen (Spicy Tonkotsu Ramen)

Experience the fiery depth of Japanese Hell Ramen. This intensely spicy noodle soup features a rich Tonkotsu broth and a homemade aromatic chili paste that will warm you from the inside out.

Ingredients

• 100 g fresh red chilies
• 12 red onion
• 12 cup neutral cooking oil
• 1 tbsp minced garlic
• 1 tbsp minced ginger
• 2 tbsp fine red chili powder
• 2 tbsp white sugar
• 4 cups Tonkotsu pork bone broth
• 2 portions fresh ramen noodles
• 2 slices chashu pork belly
• 1 soft-boiled egg
• to taste bamboo shoots (menma)
• to taste bean sprouts
• for garnish shredded scallions
• for garnish chopped green onions
• 2 sheets nori seaweed

Instructions

1. 1Blend the fresh chilies

   

   Start by preparing the base of the Hell chili paste. Place the fresh red chilies into a food processor and pulse them until finely chopped. This process will quickly break them down and release their intense heat and vibrant color.

   Tip: Remove the stems before blending. For a slightly milder paste, you can scrape out some of the seeds beforehand.
2. 2Process the red onion

   

   Next, cut a red onion into large chunks and add them to the food processor. Blend until roughly chopped. The red onion adds a natural underlying sweetness that perfectly balances the sharp, intense heat of the chilies.

   Tip: Do not over-blend the onion into a watery puree; you want to maintain a bit of texture for the finished paste.
3. 3Heat the cooking oil

   

   Place a wide pan or wok over medium heat and pour in a generous amount of clear cooking oil. Allow the oil to heat up gradually. You will need enough oil to adequately fry the aromatics and preserve the chili paste later.

   Tip: Use a neutral oil like canola, vegetable, or peanut oil so it doesnt overpower the natural flavors of the chili paste.
4. 4Test the oil temperature

   

   To check if the oil is hot enough for frying, dip the tips of wooden chopsticks into the center of the pan. When you see small, rapid bubbles forming around the wood, the oil has reached the ideal frying temperature.

   Tip: If the oil starts smoking, it is too hot. Remove the pan from the heat for a moment to cool before adding your ingredients.
5. 5Fry the blended chilies

   

   Carefully pour the freshly blended red chilies from the plate directly into the hot oil. Stir continuously to prevent them from burning and to allow the chilies to release their vibrant red pigment and spicy aroma into the oil.

   Tip: Stand back slightly when adding the chilies, as the moisture can cause the hot oil to splatter and release strong, spicy fumes.
6. 6Mix in the minced garlic

   

   Once the chilies are frying gently, add a heaping spoonful of minced garlic to the bubbling chili oil mixture. Stir it in well so the garlic cooks evenly, infusing the spicy base with a deep, savory aroma.

   Tip: Keep the heat at a moderate level so the garlic turns golden and fragrant without turning bitter from burning.
7. 7Add chopped purple onions

   

   Carefully slide the finely chopped purple onions from the plate into the pan of bubbling hot chili oil. Gently stir them into the base so they begin to soften and release their sweet, aromatic flavor into the fiery oil.

   Tip: Chopping the onions finely ensures they meld seamlessly into the paste and avoids large, chunky textures in your final ramen broth.
8. 8Add the minced ginger

   

   Once the red chilies, garlic, and onions are cooking together in the hot oil, mix in the minced ginger. Stir the aromatics well to release their fragrant oils and build the complex flavor profile of the Hell chili paste.

   Tip: Cook the ginger and other aromatics gently over medium heat to avoid burning, which can introduce an unwanted bitter taste to the chili paste.
9. 9Incorporate fine chili powder

   

   Add a generous spoonful of fine red chili powder directly into the simmering onion and chili oil mixture. This powder will deepen the crimson color of the paste and bring the intense, signature heat required for Hell Ramen.

   Tip: You can adjust the amount of fine chili powder depending on your heat tolerance, but authentic Hell Ramen relies heavily on this fiery addition.
10. 10Simmer and stir the paste

    

    As the paste cooks down and deepens in color, continuously stir it with wooden chopsticks. Keeping the mixture moving prevents the spices and sugars from sticking and burning at the bottom of the pan while the flavors concentrate.

    Tip: Keep your heat at a moderate to low level during this stage. Chili powder can burn quickly and turn bitter if the oil gets too hot.
11. 11Sweeten to balance the heat

    

    Sprinkle spoonfuls of granulated white sugar evenly over the bubbling red chili paste. The sweetness is crucial to round out the harsh edges of the spice and balance the intense heat with a subtle savory depth.

    Tip: Stir the paste thoroughly after adding the sugar until all the crystals have completely dissolved into the hot oil.
12. 12Blend into a smooth Hell paste

    

    Allow the cooked chili mixture to cool completely, then transfer it into a tall food processor or blender cup. Pulse and blend the mixture until it turns into a thick, homogenous, and smooth paste ready to flavor your ramen.

    Tip: It is extremely important to let the oil and chili mixture cool down before blending. Blending hot liquids can cause pressure buildup and dangerous splatters.
13. 13Add chili paste to the bowl

    

    Place a generous spoonful of the prepared Hell chili paste into the bottom of an empty serving bowl. This forms the concentrated spicy base for your ramen broth.

    Tip: Adjust the amount of chili paste depending on your heat tolerance. You can always add more later if needed.
14. 14Pour in the hot broth

    

    Pour the steaming hot, rich Tonkotsu pork bone broth directly over the chili paste in the bowl. The heat will activate the aromatics in the paste and create a vibrant, spicy red soup base.

    Tip: Ensure the broth is piping hot so it properly blooms the chili paste and thoroughly combines the flavors.
15. 15Add the ramen noodles

    

    Using chopsticks, carefully lower your cooked ramen noodles into the hot, spicy red broth. Let the noodles naturally fold and settle into the center of the bowl.

    Tip: Cook the noodles slightly al dente, as they will continue to soften once submerged in the hot broth.
16. 16Top with chashu pork

    

    Gently place a slice of seared chashu pork belly on top of the noodles. The rich, savory fat from the pork will slowly melt into the spicy broth, enhancing the overall flavor.

    Tip: Briefly searing the chashu slice with a blowtorch or in a hot pan before adding it to the bowl will elevate its flavor. Now is also the perfect time to finish your bowl with the halved soft-boiled egg, bamboo shoots, bean sprouts, scallions, and nori.
