Clean and wash the passion fruits and cut them into small pieces(anyshape). Add some salt into these pieces and mix it well and keep it separately for about a day or at least for 10 – 12 hrs.
At the time of making the pickle, heat a frying pan/cheenachatti and roast the mustard seeds, fenugreek seeds and cumin seeds. When colour of these ingredients turns into golden brown, put off the stove and allow to cool for some time. Then grind them into a powder/granules form and keep it aside
Heat about 3 to 4 tsp of oil in a cheenachatti, add some mustard seeds and allow to burst, and then add ginger, green chilli and garlic pieces along with curry leaves and stir it well.
When colour of these ingredients turn into golden/brown, add about 1 tsp red chilli powder, ½ tsp turmeric powder and required quantity of salt and water along with passion fruit pieces and boil for some time in low flame.
Then add about 2 – 3 tsp vinegar, asafoetida powder and the masala powder or granules(already prepared) and boil this mix for about another 10 more minutes.
After about 10 minutes, put off the stove and keep the pickle for some time to cool. Passion Fruit Pickle is ready. This Passion Fruit Pickle can be served with cooked rice or rice gruel etc.
