Indian Cucumber pickle

This is also my mama's recipe. We call it as " Dosakaya Avakaya". This is made with yellow coloured cucumber but not with regular green cucumber. Its shelf life is supposedly of 1 month. But for me, it has been 4 months I made this pickle, and even now, it is tasting good.
Preparation time: 15 min.
Ingredients:
Cucumber: 1 ( cut them into 1/2" cubes)
Red chili powder: 1 cup
Salt: 1 cup
Mustard powder: 1 cup
Fenugreek seeds: 1/4 cup ( make them into fine powder)
Turmeric: 1/2 tsp
Oil: 2cups
Method:
In a moisture-free bowl, mix all the above said ingredients well.
Transfer this into a dry jar preferably air tight glass jar.
Pour 1 tbsp of oil over the top of the pickle.
This tastes good with a no. of dishes.
