What are Mustard Seeds?
Mustard seeds come from the mustard plant, a member of the Brassicaceae family, which also includes cabbage, broccoli, and radishes. They are tiny—usually 1 to 2 millimeters in diameter—but are filled with rich oils, pungent compounds, and nutrients.
There are mainly three types of mustard seeds:
- Yellow/White Mustard Seeds (Sinapis alba): Mild flavor, commonly used in American mustard sauces.
- Brown Mustard Seeds (Brassica juncea): Spicier, popular in Indian cooking and Asian cuisines.
- Black Mustard Seeds (Brassica nigra): Strong, sharp flavor, used widely in Indian tempering and traditional medicine.
While they look small and ordinary, mustard seeds are powerful. They are used in cooking, pressed for mustard oil, and ground into the paste that forms mustard condiments.
