....and of course a little cooking oil, salt and sugar to taste.
Steps...firstly, fry the shallots, garlics and chillies till fragrant. Then, pop in the soya bean paste. Mix well and then put in the small shrimps. Lastly the cut bittergourds. Add some salt and sugar to taste. Wait till the bittergourds are half-cooked (my style, to maintain the crunchiness) and the gravy thickens. 
Last but not the least, enjoy!!
A little info about the nutritional benefits of eating bitter gourds
