For Kurma's version, you again slice your lime into 8. Then you make a mixture with chilli (cayenne pepper), ground black mustard seed and tumeric.
Layer the limes in a bottle and sprinkle with the spice mixture.
Then make a mixture of 1 cup brown sugar, to 1/2 cup lime juice and boil for 2 minutes. When lukewarm pour into bottle.
Put out in sun... every day it seems for 5-6 weeks... stay posted!
