The biggest problem for me was to get a bottle of Oyster Sauce. A few things I did which I will not do next time are
1) Not to use de-veined frozen prawns (already mentioned by Madhu, but I did not because fresh prawns are not always available in Nagpur if something like this has to be made in a hurry)
2) Make it a wee bit more hot
3) Make proper Veg fried rice as accompaniment – we had it with plain rice which was not bad except that we ended up eating just the peppery prawns.
The recipe does not mention putting a pinch of salt (or salt to taste) I realised while making and had put it but it wont strike those who do not cook on a regular basis (or are not women 😉
