“Paprika is a ground spice made from dried red fruits of the larger and sweeter varieties of the plant Capsicum annuum, called bell pepper or sweet pepper.” Wikipedia
Paprika is not a particularly savory spice. It’s used mostly to add color to spices and food without using unnatural products. It is also used as a garnish in things like deviled eggs to add a pleasing colorful aesthetic. Some smoked varieties add smoky flavor to food.
Paprika is also rich in vitamins A, B6 and E.
