Following the order of the ingredients provided, place all ingredients except the lemon juice and tomato paste into the inner liner of your Instant Pot. You want to start with the liquid, onions, and spices at the bottom before you put in the frozen okra on top.
Cook on high pressure for 2 minutes, and then allow the pot to sit undisturbed for 5 minutes.
Release all remaining pressure.
Open the lid, add tomato paste in water and lemon juice, and stir gently before serving.
