In addition to sourcing high-quality paprika peppers, it is important to work with suppliers who use safe and effective solvents for extracting the pigments and essential oils from the peppers. Ethanol and acetone are commonly used solvents in the extraction process, and suppliers should ensure that the solvents are properly distilled and purified to meet food safety standards.
Sweet paprika is the most common and available type, at least in North American supermarket spice aisles. If a recipe, or a spice bottle, simply says paprika without specifying which kind, it refers to the sweet kind. Sweet paprika has a very mild, sweet flavor and imparts a reddish hue to whatever it's sprinkled on or mixed into.
