After a while of using spices in your food, you can get bored of the predictable taste that these spices give to the dish. One of my neighbors shared this tip with me.
You can try replacing herbs and spices required to be put in recipes with some other things such as Marjoram instead of oregano, savory in place of thyme, cilantro instead of parsley, and anise seed instead of fennel. Other than Indian dishes, limit the number of spices to three at a time.
This way you can gain expertise in food preparation and you can surprise your guests at the party!
