Paprika is also known as that red stuff people sprinkle on deviled eggs.
It can be sweet, hot, or smoky. Most are labeled as such. It's bright red in color, and is used for both color and flavor.
It is necessary to make goulash.
Also very good with roast potatoes, as part of a dry rub, a garnish for potato salads or other creamy concoctions, or in soups and stews.

: "Also, it's a great way to kick up your hamburgers. Just sprinkle some on either the raw meat before mixing or across the top when on the grill. It's great!"
