Ingredients
250 gm carrots
3 Tbsp powdered mustard seeds
1 Tbsp chilli powder
1 Tbsp salt
1/2 cup mustard oil
Method
Peel the carrots, and cut them into 7cm/3″ pieces, not too thin (about finger size, you can say).
Mix all ingredients together, and put the mixture into a clean jar with a tight lid.
Leave in the sun for about a week and shake the bottle once a day to mix well.
