Paprika is a spice made from dried red peppers that are ground into a powder. Depending on what type of paprika it is, it'll be made from a different variety of red pepper. It has a sweet, pungent, earthy, and somewhat fruity flavor, and varying levels of heat, ranging from the most common very-mild type to the less popular pretty-hot. Good paprika should have a pronounced aroma that you'll notice when you take a whiff from the jar, and it needs to be thrown out after six months as it will lose its potency over time.
