Instructions
- Place pig trotters and chicken backs in a pot on stove of boiling water, reduce temperature to simmer. Simmer for a minimum of 10 minutes, skimming off foam as it cooks. Remove trotters and backs, set aside, discard liquid. Pick out any dark or bloody bits from trotters and backs.
- Place trotters, backs, leeks, shallots, ginger, mushrooms, and pot belly in instant pot. Close pot and cook on "soup/broth" setting for 2.5 hours.
- Place soy sauce, mirin and 4 Tbsps water in ziplock bag, place eggs in bag, and place in refrigerator, turn occasionally (can be done night before).
- After 2.5 hours, release pressure and open. Remove belly, wrap tightly in cling film wrap and place in refrigerator. Close Instant Pot back up, set for another 60 minutes on "soup/broth" setting.
- Once done, release pressure, then strain broth and throw out solids.
- In separate pot on stove, boil water. Using a small mesh strainer, cook ramen in water until done, remove and strain, and place in bowls. Using same mesh strainer, cook bok choy leaves in same pot of boiling water for 30-60 seconds, strain.
- Take pork belly from refrigerator, remove cling film and slice thinly. Arrange pork belly, bok choy, corn and green onions in bowl over ramen noodles. Ladle hot broth over other ingredients, top with halved eggs and serve.
And now for the details…
Ramen. Delicious, delicious ramen. Until about a decade ago, I had no idea what real ramen was or could be. Before that, my brain associated the word ramen with Mr. Noodles or Ichiban, and I had no idea that there was so much more that ramen had to offer than instant noodles.
Since then, I have sought out ramen wherever I may roam. My favourite that I have tried so far is from the chain Tenkaippin in Japan. We made return trips to the same restaurant in Kyoto, several years ago. The broth is super flavourful, thick and rich. I have dreams about it even still. This recipe… is not that soup unfortunately. But, it is a nice rich broth that is pretty tasty, if I do say so myself. Cooking for an extended period of time in the Instant Pot is allowing the collagen to release from trotters and chicken backs, providing a thick mouth feel.
Let’s get started. We will start by “cleaning” the pig trotters and chicken backs. Bring a pot to a rolling boil and add the trotters and backs. Reduce to a simmer and cook for around 10 minutes, skimming off any gunky foam off the top. Once that’s done, dump the liquid. Using a fork, knife, or chopstick, we are going to pick at the trotters and back, removing any darkened bits or pieces that obviously have blood. We are doing this to clean out any bloody bits so we have a nice clear broth, rather than a skanky, cloudy, dark broth.
Once cleaned, place the trotters and backs in your instant pot. Stack in the leeks, shallots, ginger, and mushrooms. We are also going to roll the pork belly pieces and tie them tight with butchers twine, and place that in the pot with everything else.
Fill the pot with water up to the “MAX” line, and then close the pot, ensuring it is in the “Sealing” position and set for 2.5 hours on the “Soup/Broth” setting.
While the broth is cooking, we’ll set the eggs to marinating. We are making ajitsuke tamago, or seasoned eggs, to add to the ramen later. Mix the soy sauce, mirin, and 4 tablespoons of water in a ziplock bag, and then place your soft boiled eggs inside (need a refresher on how to soft boil an egg? Directions are included in this recipe). Close the ziplock up tight so as little air as possible is left inside, and then place in the fridge. Turn them around after an hour or two so they marinate evenly on all sides.
After 2.5 hours of cooking, release the pressure from the pot, and open ‘er up. Remove the pork belly, then close the pot back up, including resetting to “Sealing” position and set the pot back to “Soup/Broth” setting and cook again for 60 minutes. Wrap the pork belly tightly in cling wrap, and place in the refrigerator. The pork belly is more than cooked by now, and chilling the belly will allow us to cut it nice and thin to place in the bowl later.
Once the broth is done, strain it into a container, and discard any solids. I like using cheese cloth to help with the straining to get rid of any small, gritty bits.
Time to get everything ready. Boil water in a pot, and place the ramen noodles in a wire mesh strainer. Dip the strainer into the pot to cook the noodles, and when done, drain the noodles and place in the bottom of a large bowl.
Using the same strainer and boiling water, cook the bok choy until the leave just turn vibrant green. Place the boy choy, green onions, and corn into the bowl. Remove the pork belly from the fridge, and take out of the cling wrap. Slice the pork belly thinly and place in the ramen bowl.
Finish the soup off by taking the eggs out of the marinating liquid, cutting in half, and placing in the bowl. Ladle the still-hot broth over the soup contents, and serve immediately. Enjoy immediately!
Happy eating.
