They’re usually sold cleaned and de-shelled, but you have to careful wash them to get rid of any residual grit and shell bits.
Here’s my adaptation of a recipe shared by a friend.
15-20 कालवं – Shelled and cleaned oysters (in a non stick pan, heat a few drops of oil, sauté a tsp of crushed garlic, some haldi, red chilli powder and salt on high heat and add the oysters. Cook for around 5-7 minutes till done.
3 medium onions
Handful of coriander leaves
1 large green chilli
1 tsp Coriander powder
1 tsp Red chilli powder
2/3 tbsp Besan

Add the chopped prepared oysters.
