You can use yesterday's cooked potatoes for this. Otherwise, peel your potatoes, cut into 1.5 cm / 0.5" dice and boil in salted water until cooked but holding their shape (about 8 minutes for the starchy Maris Piper variety). Drain and allow them to cool off completely (overnight is ideal).
Heat up a pan - I used a cast iron skillet - on a low-medium heat. Once hot add the oil and mustards seeds. Allow mustard seeds to crackle, then add cumin seeds, curry leaves and a generous pinch of salt to the oil. Fry for a few seconds before adding cubed potatoes.
Fry the potatoes until uniformly browned, giving them a good stir from time to time.
Dust finished potatoes with turmeric, garam masala and more salt if needed. Stir well to coat for a few seconds and switch the heat off so that the spices don't burn.
Drain and rinse soaked lentils.
Place drained lentils in a blender together with the rest of the ingredients (apart from oil) and approximately 300 ml / 1¼ cups of water - you may need a little less water if not using garlic or ginger. Process until smooth, the batter should be pourable but a little thicker than a crepe batter. You may need to add a touch more water if it's too thick.
Heat up a tried and tested (that's important) non-stick pan on a low-medium heat, brush it with a bit (I found ½ tsp to be enough on my ceramic pancake pan) of oil using a silicone brush.
Pour ¼ cup of the mixture onto the hot pan and use the back of the spoon to spread the mixture out in a circular fashion. Cook each pancake for about 3 minutes on one side and then flip. Cook for 2-3 minutes on the other side. If you like your pancakes crispy, spread the batter thinly and cook the pancake for a little longer.
Keep the cooked pancakes in a stack in a warm oven while making the rest.
Fill with masala potatoes, dollops of vegan cream / yoghurt, favourite chutney and heaps of fresh coriander / cilantro.
Place drained cashews, lime zest and juice, salt and pepper and about 45 ml / 3 tbsp water in a small blender (I use a Ninja blender for this).
Blend until smooth. If using a standard blender you may need to make a double quantity.
