Make jammy eggs (optional): Bring a small pot of water to a boil. Gently lower in eggs and cook 6–7 minutes. Transfer to an ice bath, peel, and set aside.
Prepare the tare: In a small bowl, stir together miso, chili-garlic sauce, and rice vinegar until smooth.
This will season the broth fast and evenly.
Sweat the aromatics: Heat neutral oil in a medium pot over medium heat. Add garlic, ginger, and the white parts of the scallions. Cook 30–60 seconds until fragrant, not browned.
Build the broth: Add broth, soy sauce, mirin, and sesame oil.
Whisk in the tare. Simmer gently for 5–8 minutes to meld flavors. Taste and adjust with soy for salt, vinegar for brightness, or a pinch of sugar if it tastes flat.
Cook the protein: If using chicken or pork, add to the simmering broth and poach until just cooked, 3–5 minutes depending on thinness.
For mushrooms or tofu, sauté in a skillet with a little oil and salt until golden, then reserve. For shrimp, add to the hot broth and cook 2–3 minutes until pink.
Blanch the greens: Stir spinach or bok choy into the hot broth for 30–60 seconds until wilted but bright.
Cook the noodles separately: Bring a second pot of water to a rolling boil. Add noodles and cook just to package directions—usually 2–3 minutes for fresh, 4–5 for dried. Drain well. This keeps your broth clear and prevents overcooking.
Assemble: Divide noodles into bowls.
Ladle hot broth, protein, and veggies over the top. Halve the jammy eggs and nestle them in. Finish with scallion greens, nori, sesame seeds, and a drizzle of chili oil.
Serve immediately: Ramen shines when hot and slurpable.
Add a squeeze of lime for a fresh pop.
