Quantities and times come from The Ramen_Lord Book of Ramen by Mike Satinover and Scott Satinover. The 2 h 15 min pressure time is calculated from the book’s conversion rule. Steps written by Samo Ramen.

Published 8 November 2026. We have not cooked this version ourselves yet, so the times are the book’s and the soup yield is unmeasured.

Time: At least 3 hours, with 2 h 15 min of that under pressure.

Bowls per batch: Soup not measured yet. The tare is enough for about 16 bowls and the oil for about 8.

Plan: Start the soup first. Make the tare and aroma oil while it cooks, then cook the noodles and fill the bowl at the very end.

## One bowl

| Component | Amount |
| --- | --- |
| Soup | 300 mL |
| Tare | 30 mL |
| Aroma oil | 15 mL |
| Noodles | 130 g |

## Ingredients

### Soup

- 2 kg pork neck bones
- 2 kg pork femurs, split
- 6 L water, plus fresh water for blanching

### Tare

- 500 g water
- 50 g salt
- 33 g MSG

### Aroma oil

## Steps

### Soup

#### 1. Blanch the bones

Put the neck bones and femurs in a pot and cover them with fresh water. Once it boils, turn it down to a simmer for 15 to 20 minutes and keep lifting off the foam.

Optional, for a whiter soup: first soak the bones in cold water for at least 6 hours, then start with fresh water.

Timer: 15 min or 20 min

Done when: Very little foam is still coming up.

#### 2. Scrub the bones

Pour everything into a colander and throw the water away. Hold each bone under the tap and rub off anything dark, including inside the cracks.

Done when: The bones are clean, with no dark bits left.

Needs first: Blanch the bones

#### 3. Pressure-cook the soup

Put the clean bones in the pressure cooker with the 6 L of water. Cook under pressure for 2 hours 15 minutes, then use a fast release.

Natural release instead: 2 hours under pressure, then 30 minutes releasing. No pressure cooker: 18 hours at a medium boil, stirring often and adding water as the level drops.

Timer: 2 h 15 min

Done when: The pressure is fully released.

#### 5. Blend the soup

Blend the strained soup for 30 seconds, starting slowly and working up to full speed. With a hand blender, go for 5 minutes instead; the result is less creamy.

Timer: 30 sec or 5 min (hand blender)

Done when: The soup looks smooth and creamy to you.

Done when: No crystals remain.

Timer: 10 min or 15 min

Done when: The scallions are pale gold and the oil smells of them.
