Black mustard seeds are the small, round seeds of the black mustard plant, scientifically known as Brassica nigra.

These seeds are commonly used as a spice in various cuisines around the world, including Indian, Middle Eastern, and Mediterranean.

They have a pungent, spicy flavor and are typically heated in oil or butter until they pop to release their full flavor.

In addition to culinary uses, black mustard seeds have been used in traditional medicine thanks to their anti-inflammatory, antimicrobial, and antifungal properties.

Nutritionally, they’re rich in selenium, omega-3 fatty acids, and magnesium, among other essential nutrients.
