For the potato puree

  1. In a large pot on the stovetop, bring water and about a teaspoon salt to a boil.

  3. Season the potatoes generously with salt. Add the cream and the butter and puree.
  4. Discard the boiling water and transfer the puree back to the pot. Hold over low heat until ready to serve.

For the reduction

  1. In a 1-quart (1 liter) saucepot over medium high heat, add the blueberries and sugar.
  2. As the sugar starts to melt, muddle the blueberries.
  3. Add a splash of soy sauce, the vegetable stock, and the sesame chili oil and cook for 2 minutes.
  4. Pour the blueberry mixture into a blender and puree.
  5. Once pureed, pour through a fine strainer or sieve back into the same saucepot and reduce over medium heat.
  6. Once reduced by half, add 1 tablespoon (14 g) of the butter and mix until melted. Hold at low heat until ready to serve.

For the vegetables

  1. In a saute pan on high heat, add a dash of grape seed oil (or any high-smoke-point cooking oil).
  2.  Add the mushrooms and shishito peppers and saute for 1 minute.
  3. Add a splash of vegetable stock and continue to cook.
  4. As the vegetable stock reduces away, add 1 tablespoon (14 g) of the butter add the (optional) dash of Togarashi, for a little kick.

Finish and serve

  1. 1. When the pork belly has cooked, remove from the pouch and reserve the pouch juices.
  2. On the stovetop, heat a fry pan over high heat until very hot.
  3. Add a dash of oil to the hot pan and sear the pork belly skin side down. After a minute of searing, add the poaching liquid from the pouch, a little at a time, and baste the pork belly.
  4. Once the skin on the pork belly is crispy, remove and plate.
