Grinding your spices with a mortar and pestle really releases loads of flavor you never knew were packed into your spices. Invest in a mortar and pestle (they’re really cheap) and you’d be surprised how much more savory your marinades and dishes will become. My family swears by this technique.  Make sure to keep it simple when you buy a mortar and pestle and stick to wooden or stone ones. Furthermore, when grinding your spices make sure to add a pinch of salt to unlock the juices in the spices
