I brought some cucumbers from the store....after cutting & tasting found it was a bit bitter.Not worth doing a raita.So came out of this idea....a pickle with it .It was good & no bitter taste at all.The lime juice removed the bitterness.
Peeled & cubed cucumber-1 big
(It was 3 hand full)
Oil -to cover the whole mixture(1/4 cup)
Dry grind to a smooth powder
Mustard-2 & 1/2tsp
In a bowl mix all above ingredients together.Pour enough oil to cover the whole mixture(oil should float on top).Store it in fridge.It will taste better to eat the next day.
Use bright red chilly powder,mine didn't give good colour.I have no idea about the shelf life.....so try to make small quantity & finish it as fast as you can.
