Prepare the Potato Straws: Peel the potatoes. Using the shredding attachment of your Kenwood Chef (or a knife), cut the potatoes into thin matchsticks (julienne). Rinse them briefly in cold water to remove excess starch and pat them very dry with a clean kitchen towel.
Air-Fry the Potatoes: Preheat your Air-fryer (or oven to 220°C). Toss the dried potato straws with 1 tbsp olive oil and a pinch of salt (and the Bratkartoffelgewürz if using). Air-fry for 12-15 minutes at 200°C, shaking the basket halfway through, until golden and crispy. Set aside. Tip: If using the oven, spread on a baking sheet lined with baking paper.
Prepare the "Egg" Mixture: In a small bowl, whisk together the oat whipping cream, cornstarch, turmeric, and a generous amount of black pepper. Set aside. This will mimic the creamy, yellow egg strands of the original dish.
Cook the "Bacalhau" Base: While the potatoes are frying, heat 2 tbsp olive oil in a large pan over medium heat. Add the sliced onions and a pinch of salt. Sauté for 5-6 minutes until soft and translucent. Add the minced garlic and cook for another minute.
Add the Tofu & Umami: Add the diced smoked tofu and the crumbled natural tofu to the pan. Sauté for 3-4 minutes until the tofu starts to brown slightly. Stir in the seaweed flakes and the no-fish sauce. Cook for another 2 minutes to let the flavors meld.
Combine and Bind: Reduce the heat to low. Pour the "egg" cream mixture into the pan, stirring gently and continuously. The mixture will thicken quickly and coat the tofu and onions, creating a creamy sauce. Do not overcook, or it may become too thick; it should look like curds of egg.
Final Assembly: Remove the pan from the heat. Gently fold in the crispy potato straws (reserve a small handful for garnish) until they are coated in the creamy mixture.
Prepare the Side: Quickly steam the broccoli florets in a pot with a little water for 3-4 minutes until tender but still bright green. Drain.
Serve: Divide the Bacalhau à Brás among four plates. Top with the reserved crispy potato straws, sliced black olives, and plenty of fresh chopped parsley. Serve with the steamed broccoli and a lemon wedge on the side.
