For preparing mango peanut chutney, first heat oil in a pan and splutter mustard seeds.
Add fenugreek seeds, broken red chillies, ginger and asafoetida. Stir fry in low flame and remove from fire. Allow tempering ingredients to cool.
Transfer tempering ingredients into a blender and grind well. Stir in roasted peanuts, chopped mango, sugar and required salt. Blend again to a smooth paste.
Mango peanut chutney, a yummy side dish with idli or dosa, is ready.
