Things to keep in mind with Okra so its not slimy-Dry the Okra before cutting.
Its important to not add salt in the beginning as we normally do for all vegetables as we don't want it to release moisture.
Always add something sour, we added Amchur. This helps to make a drier okra sabzi. In the south in USA, vinegar in Okra is common, though I have never tried that.
If you are preparing the night before, spread Okra sabzi on a baking sheet and bake/ broil just before serving.
Since I made it right before serving, I didn't need to bake it,but I have done it on other occasions.
