Spread the potatoes on a baking sheet. Use the bottom of a jar or glass to gently crush them until they burst but remain in one piece (as much as possible).
If baking, place the seasoned potatoes in the oven and bake until crispy, about 20 minutes. If air frying, place the potatoes in the air fryer basket and cook until crispy, also about 20 minutes.
While the potatoes cook, combine the shallots and lime juice in a small bowl. Set aside for the shallots to pickle slightly for 5 mins.
2 eschallion shallots, Juice of half a lime
Add the vegan kewpie mayonnaise (or regular vegan mayo), gochujang paste, vegan fish sauce and coriander leaves. Whisk to combine.
8 tablespoon vegan kewpie mayonnaise, 1-2 tablespoon gochujang paste, 2 teaspoon vegan fish sauce, Small bunch fresh coriander leaves
Once crispy, remove the potatoes from the oven/air fryer and let them cool slightly, about 5 minutes.
Transfer them to a serving plate or salad bowl.
Dress the potatoes with around half of the sauce. Sprinkle with the finely chopped chives and toasted black sesame seeds (optional) and serve with the remaining sauce on the side.
Small bunch fresh chives, 1 teaspoon toasted black sesame seeds
