When you first hear the sound of the mustard seed “popping,” add the curry leaves. Add the cut chayote into the inner pot, add salt and add ¼ cup of water to moisten the mixture. Cook the vegetable until it is partially cooked (until it is just starting to get soft) and press ‘cancel’ to shut down the heating. Turn on the IP to ‘slow cooking’ high and set the time for 30 minutes.
