Some ideas for flavorings I have tried are:
Asian - ginger and garlic with jasmine rice
Caribbean - black pepper, oregano, cumin, cayenne pepper, paprika, and dried cilantro with medium and long grain
Cajun - black pepper, garlic powder, onion powder, oregano, thyme, creole seasoning, and file with long grain
This recipe is based on information from
Dan Souza's video for America's Test Kitchen.
