Tonkotsu Ramen

Tonkotsu ramen is Japan's legendary creamy pork-bone soup, famous in Fukuoka, with a broth simmered until the bones release their richness and turn the soup milky white. This home-friendly version uses pork neck bones and a pressure cooker to achieve that deep, silky body in hours instead of all day. Served over springy ramen noodles with tender chashu pork, a soft marinated egg, and crisp toppings, it is pure comfort in a bowl.

Ingredients

• 1.5 kg pork neck bones, split and rinsed
• 1 pork trotter (about 400 g), rinsed
• 3 liters water, plus more as needed
• 1 large onion, halved
• 1 knob ginger (about 50 g), smashed
• 1 whole head garlic, halved crosswise
• 4 spring onions, roots trimmed
• 500 g fresh ramen noodles
• 400 g rolled chashu pork belly (store-bought or pre-made)
• 4 ajitama (marinated soft-boiled eggs)
• 80 ml shoyu tare (seasoned soy sauce)
• 40 ml mayu (black garlic oil)
• 4 sheets nori seaweed
• 2 spring onions, thinly sliced, for topping

Instructions

1. Place the pork bones and trotter in a large pot, cover with cold water, and bring to a rolling boil for 10 minutes to purge impurities. Drain, rinse the bones well under running water, and scrub the pot clean.
2. Return the bones to the pot with the onion, ginger, garlic, spring onions, and 3 liters of fresh water. Bring to a hard, vigorous boil over high heat — this aggressive boil is what makes the broth creamy white.
3. Maintain the hard boil for 2 to 2.5 hours, topping up with hot water whenever the level drops. Skim off any dark scum that rises but keep the bubbling strong.
4. Strain the broth through a fine mesh sieve into a clean pot, pressing gently on the solids. Keep the broth at a low simmer; it should be opaque, creamy, and coating the back of a spoon.
5. Cook the ramen noodles in a separate pot of boiling water for the time on the package, usually 2 to 3 minutes for fresh noodles. Drain well and shake off excess water.
6. Add 20 ml of shoyu tare and 10 ml of mayu to each warmed serving bowl, then ladle in about 450 ml of hot tonkotsu broth and stir.
7. Divide the noodles among the bowls. Arrange 4 to 5 slices of chashu pork, half a marinated egg, a sheet of nori, and a handful of sliced spring onions on top.
8. Serve immediately while the broth is steaming and the noodles are springy — tonkotsu waits for no one.

Pro tips

• A pressure cooker cuts the broth time to about 90 minutes at high pressure; just keep the lid seal tight and do a natural release.
• Never let the broth sit on low heat too long before serving — the rolling boil is what builds the creamy body.
• Warm your bowls with hot water before assembling so the broth stays hot at the table.
• Store leftover broth in the fridge for up to 3 days or freeze for a month; it will set like jelly, which means plenty of collagen.
• If the broth tastes flat, add a little more tare at the table rather than over-salting the whole pot.
