Instant Pot Tonkotsu Ramen Broth Base

Follow our step-by-step guide on how to make Instant Pot Tonkotsu Ramen Broth Base.

1. Step 1

   To create a delicious tonkotsu broth, start by placing your pork bones in a large pot and covering them with water.

2. Step 2

   Bring the water to a boil over medium-high heat and let it bubble away for about five minutes.

3. Step 3

   This initial boiling helps to remove impurities, so don’t skip this step! After five minutes, drain the bones in a colander and rinse them under cold water until the water runs clear.

4. Step 4

   This ensures a clean and flavorful broth.

5. Step 5

   Next, grab your Instant Pot and turn it on, selecting the 'Sauté' function.

6. Step 6

   Pour in some olive oil and let it heat up.

7. Step 7

   Add in the chopped leeks, onion, and minced garlic, and sauté everything for about seven to ten minutes.

8. Step 8

   You want the onion to become translucent and start to brown, which adds a lovely depth of flavor.

9. Step 9

   Once that’s done, turn off the 'Sauté' mode.

10. Step 10

    Now it’s time to add the cleaned pork bones back into the pot, layering them over the sautéed vegetables.

11. Step 11

    Pour in four cups of water, then secure the lid on your Instant Pot, making sure the vent is set to 'Sealing'.

12. Step 12

    Select 'High Pressure' and set the timer for 45 minutes.

13. Step 13

    As the pot heats up, it will take about ten to fifteen minutes for the pressure to build.

14. Step 14

    When the cooking time is up, you can release the pressure using the natural-release method, which may take anywhere from ten to forty minutes.

15. Step 15

    If you’re in a hurry, carefully switch the vent to 'Venting' for a quicker release.

16. Step 16

    Once the pressure is fully released, remove the lid and gently take out the inner pot.

17. Step 17

    To strain the broth, place a cheesecloth-lined colander over a large saucepan and pour the broth through it.

18. Step 18

    This will catch any solids, leaving you with a beautifully clear liquid.

19. Step 19

    Discard the solids and set the strained broth aside.

20. Step 20

    If there’s any meat left on the bones, shred it and keep it for later.

21. Step 21

    Now, let’s season that lovely broth! Add salt and pepper to taste, then stir in the dashi granules along with one more cup of water.

22. Step 22

    Pour in some soy sauce and bring the broth to a gentle boil over medium-low heat.

23. Step 23

    Once it’s bubbling, reduce the heat to a simmer.

24. Step 24

    In a separate bowl, scoop out about one-third cup of the broth and mix in the shiro miso until it’s fully dissolved.

25. Step 25

    Return this mixture to the saucepan and give it a good stir.

26. Step 26

    Toss in some fresh spinach and let everything simmer for another ten minutes, but be careful not to let it boil.

27. Step 27

    While your broth is simmering, bring another pot of water to a boil.

28. Step 28

    Cook the ramen noodles according to the package instructions, which usually takes about two minutes.

29. Step 29

    Once they’re done, drain and rinse them under cold water to stop the cooking process.

30. Step 30

    To serve, place a generous handful of noodles in each bowl, ladle the hot tonkotsu broth over the top, and finish with the reserved pulled meat and a handful of spinach.

31. Step 31

    Enjoy your homemade tonkotsu ramen, and savor the rich flavors that come from your hard work!.
