This is a spicy and extremely flavourful way of serving fries/chips. The sauce can be prepared in advance and frozen or refrigerated until needed.
Heat the margarine with the oil in a wok or pan until hot. Add the ginger and cook until fragrant, then add the vinegar and salt, simmer for a minute then add the paprika, red chilli powder, tandoori powder, cumin, pepper and lemon juice. Remove from the heat and sprinkle the cinnamon powder. Stir together.
