Although the word 'aviyal' denotes mixture of vegetables, this side dish is made with green (raw) plantain alone. Plantain is cooked with green chilli, kudampuli (malabar tamarind or gambooge), turmeric, curry leaves and salt. Grinded mixture of coconut, cumin seeds and pearl onions (shallot) are added and cooked. The dish is finished off with a dash of oil and curry leaves. Kudampuli can be removed from the dish after cooking to avoid too much sourness in localized areas since it is a dry curry.
