Peel the potatoes and cut them into large cubes. Boil them in salted water until soft.
Chop the garlic and the fresh herbs.
Drain the boiled potatoes and mash them through a sieve or with a potato masher. Add the plant milk and stir until the mash is smooth. Make a small well in the center of the potatoes and sprinkle in the baharat and the cumin seeds, but don’t mix them yet.
Heat the olive oil in a small pot and gently fry the garlic and chopped herbs for about 5 minutes until fragrant.
Pour the hot oil directly from the pot over the spices sitting in the well of the mashed potatoes. Let it sizzle until the sound stops. Add a generous pinch of salt, then stir everything together until the mash is evenly seasoned and smooth.
Mix the harissa with a little olive oil and half a lemon's juice and drizzle it over the top of the mashed potatoes. Serve warm and enjoy!
