Soak Dried plums overnight in enough water. Next day de-seed the dried plums.
Chop fresh plums, green chillies.
Heat oil in a pan, add asafoetida, cumin, mustard, nigella, fennel and fenugreek seeds. Once these crackle, add green chillies and ginger. Sauté for 30 secs.
Add the dried, soaked and de-seeded plums and the fresh plums. Let it cook on low flame until it releases juices and turns soft. Add water and cook for another 5-7 mins. At this stage, if you like smooth chutney instead of chunky, then take it off the flame, cool it a bit and then using an immersion blender, blend it to desired consistency. Take it back to the flame.
Add the powdered spices, dried mint and salt. Mix well.
At this stage taste the mix and add jaggery only if required (dried plums once soaked are sweet enough, I also used sweet fresh plums to avoid additional sweetener).
Cover and cook until it reaches the desired consistency (approx 2-3 mins). Take it off the flame. Add lemon juice and soaked basil seeds.Let it cool to room temperature. Store in an airtight container in refrigerator. Enjoy!!!
