Gobi-gajar-shalgam achar

One of my most vivid memories of the first week as a new bride in my marital home is of breakfast. Thankfully, those were the days before size zero brides, and I had no qualms about wolfing down steaming hot stuffed paratas with gobi-gajar-shalgam achar. Seeing their "Madrasi" bride tuck into the typically Punjabi breakfast must also have reassured my in-laws about my ability to fit into a new culture.
Unfortunately, however, that was the first and last time I got to eat gobi-gajar-shalgam achar. My mother-in-law didn't make it herself, and the stuff you got at restaurants was at best a poor attempt at replicating the classic dish.
This winter, I was determined to attempt the recipe myself, and before I could change my mind, bought the ingredients, and even cut the vegetables and kept them to dry. It was easier than I expected, and I wonder why I never attempted it all this while.

1 Kg vegetables (a mix of cauliflower florets, carrot slices, turnip cubes)
65 gms mustard seeds
65 gms salt
150 gms jaggery
150 gms mustard oil
150 gms vinegar
5 tsp Garam masala
100 gms ginger-garlic paste
25 gms red chili pwdr

Method:
Cut the vegetables, and leave them out to dry for 6 hours (I put them in a preheated oven with the heat off).
Heat the mustard oil, let the mustard seeds splutter.
Add the vegetables, fry the vegetables lightly and keep aside.
In the same oil, add ginger-garlic paste, and saute till the raw taste goes.
Meanwhile, heat the vinegar in a pan, add the jaggery, and stir on a low heat till the jaggery dissolves completely. Turn off the fire, and let it cool down.
Mix all the ingredients, including the dry masala. Pour into a sterilized jar, cover the mouth with a piece of cloth, and keep in the sun for a week.
