Start by washing and drying the Okra, then place in a flat dish, spread them all over so as not to be stacked on each other, and drizzle on top with the white vinegar. Place in the sun for an hour.
In a medium pot filled to 2/3 with salted water add the edamame beans and bring water to a boil and simmer for 8 minutes. With a slotted spoon take out of the water in a bowl filled with water and ice cubes to stop cooking and then to a colander to allow to drain.
Take a large sauté pan and place on medium fire. A minute later add the bacon and sauté until a bit browned and crispy. Remove to a plate with a paper towel to drain.
In the same pan with the fat of the bacon add the scallions on medium heat along with the cut okra and cook for 10-12 minutes until a bit soft. Lightly season with salt & pepper and deglaze with the balsamic vinegar. Remove from the pan and keep aside.
Once again in the same sauté pan, place it on medium heat and a minute later add the oil. When it heats up and smokes add the corn and allow to char without moving. Once charred, toss add the chilli peppers and char a bit more. Lightly season with salt & pepper and deglaze with the soy sauce. Remove from the pan and keep aside
In the meantime, we place a small sautéing pan over low-medium heat and add the butter and the sugar. Once melted and frothed we add the walnuts and stir well to get well coated. Cook for 5-7 minutes until nicely colored and caramelized.
We build our dish by adding all the above into a bowl, the Okra, edamame beans, sweet corn and chilli peppers, walnuts as well as the bacon and parsley. Toss couple of times, season with more salt and pepper if necessary and serve.
