Assembly
Step 1
Preheat oven to 425ºF.
Step 2
In a 10-inch cast-iron skillet (see note) over medium heat, add kimchi and brine. Once kimchi has softened slightly, add onion, green onion, potatoes, gochugaru, gochujang, sesame oil, water, and Shio Ramen Broth Concentrate. Cover and bring to a boil, then reduce to a heavy simmer. Remove cover and simmer until the potatoes are cooked through, about 12-15 minutes.
Step 3
Add pork belly and simmer until cooked. Reduce to low heat and add cream and milk. Stir.
Step 4
Create a slurry with the cornstarch and some water. Slowly add to the stew while stirring and continue to heat on low until lightly thickened. Add cheese and stir until melted.
Step 5
Roll out puff pastry and brush with egg wash. Sprinkle on sesame seeds.
Step 6
If you did not use a 10-inch cast-iron skillet, transfer the stew to a heat-proof dish of your choice. Carefully lay the puff pastry on top, making sure it’s just large enough to have some overhang to account for shrinkage in the oven.
Step 7
Bake for 20-25 minutes, or until puff pastry is golden brown and crispy. Let sit for at least 5-10 minutes before serving.
Note:
You can also use separate individual dishes or a pie dish, rather than a cast-iron skillet, if you prefer. The filling can be cooked in a saucepan or pot separately, then cut the pastry dough to size appropriately to the dish so that it hangs over slightly to account for shrinkage during baking.
