In a large bowl, add 2 large onions, finely sliced, 1 medium potato, finely chopped, 1 small handful fresh spinach leaves, roughly chopped, 1 small handful fresh coriander leaves and stalks, roughly chopped, 1/4 teaspoon cumin seeds, 1/4 teaspoon cumin powder, 1/4 teaspoon coriander seeds, 1/4 teaspoon coriander powder, 1/2 teaspoon garam masala, 1/4 teaspoon turmeric, 1/4 teaspoon mild red chilli powder, 1/2 teaspoon dried fenugreek leaves, 1 teaspoon garlic ginger paste, 1/4 teaspoon sea salt and 2 teaspoons fresh lemon juice. Mix well and set aside for 1 hour. During this time, the salt will draw water from the vegetables, reducing the amount of added water required; this increases the flavour of the finished pakoras.
After pakora mix has rested for 1 hour, heat oil for deep frying to 170C/340F. If using a fryer with a basket, remove the basket before heating the oil to prevent pakoras from sticking to the basket. Add 100g gram flour and 3-4 tablespoons plain flour to prepared pakora mix, then slowly add 2-3 tablespoons water. Mix well and add a little more water or flour as necessary until pakora mix has a slightly thick consistency and falls slowly off of the back of a spoon.Carefully drop spoonfuls of vegetable pakora mix into the hot oil and fry pakoras in batches for 3-4 minutes, turning occasionally until golden and crisp. Using a slotted spoon, lift pakoras from the oil and transfer to a plate. Leave to stand for 5 minutes, or if you prefer at this stage set aside to cool completely, ready to fry again when you choose.
To finish vegetable pakoras, heat oil for deep frying to 180C/350F. Carefully drop vegetable pakoras into hot oil and fry for 2 minutes until hot and crunchy. Use a slotted spoon to remove pakoras from the oil, drain off any excess and arrange pakoras on a serving plate. Garnish with 1/2 small onion, finely sliced and 1 small handful fresh coriander leaves, roughly chopped and serve with pink pakora sauce and a lemon wedge.
Notes
For ease, a handful of frozen chips can be used instead of the potato in this recipe. Remove the chips from the freezer and set aside at room temperature for a short time until they're defrosted enough to be sliced thinly.
