A friend would send this sauce and some delightful kachoris over once in a while. Though I loved the kachoris, the sauce is what I craved. I finally got the recipe and here it is!
Warning: the chutney/ sauce has a raw mustard taste that is pretty spicy but so delicious
Pooja’s Mustard Chutney
100 g yogurt (strain out water for 10 mts)
4 green chillies
½ tsp mustard sauce
1 T mustard oil
Steam green chillies (add chillies to boiling water, cover with lid and leave for 2 mins).
Remove from pan and de-seed.
Mix chillies with a little yogurt and blend tog in a mixer.
Then add the mustard oil, mustard sauce and rest of the yogurt. Adjust salt according to taste and enjoy.
