Preheat the oven to 220°C. While it's heating up, make the soured cream. Place the cashews in a blender with the measured water, lime juice, vinegar and jalapeños. Season and blend for at least ten minutes, or until completely smooth. Scrape down the sides with a spatula every few minutes, bearing in mind that the cream will go through several stages until you achieve the desired smooth consistency. Transfer to a bowl and refrigerate until needed.
Place the potatoes in an ovenproof dish and sprinkle over the cinnamon, cumin and coriander, then drizzle with the maple syrup and 2 tablespoons of the oil. Season generously and toss to combine. Roast in the oven for 35–40 minutes, or until golden and crisp, shaking the pan from time to time. Remove from the oven, season and toss through the chopped coriander and lime zest.
To make the salsa, place the sweetcorn kernels in a large bowl with the chopped radish, celery, spring onion and chilli. Add the lime zest and juice, season generously and stir to combine. Add the parsley and dill, stir and set aside until needed.
Heat the tortillas on a lightly oiled griddle pan and keep warm in a clean tea towel. Spread each tortilla with a light smear of soured cream, then top with some rocket leaves. Followed by crispy potatoes, sweetcorn salsa and some more soured cream. Finish with a squeeze of lime juice, dust with cinnamon and serve.
