Mustard seed
Mustard seeds are the small, round seeds of the mustard plant (Brassica nigra, Brassica juncea, or Sinapis alba). The herb has been used for thousands of years and forms the basis for mustard, but also as a spice in dishes, for pickling vegetables, or in combination with meat and cheese. The flavor is sharp and spicy, with mild to spicy notes depending on the type of seed.
Characteristics of mustard seeds
The mustard plant is an annual plant with bright yellow flowers. The seeds ripen in narrow pods. Mustard seeds are harvested when the pods are fully developed but not yet bursting. There are three main types:
- Yellow mustard seed (Sinapis alba): mild flavour, larger seeds, widely used in European mustards
- Brown mustard seed (Brassica juncea): cross between black and yellow, slightly spicier, easy to grow and harvest
- Black mustard seed (Brassica nigra): small, intensely pungent seeds with a high oil content, often used for strong mustard
The origin of mustard seed
The original mustard seed varieties originated in the Mediterranean region and parts of Southern Europe and Asia. Black mustard was already used in India around 3000 BC. Greeks and Romans knew the spice as sinapis and used it to flavor dishes. The name mustard likely derives from the use of must, unfermented grape juice, and the Latin word ardere, meaning to burn. Mustard became a popular product in Europe during the Middle Ages, with cities like Dijon playing a significant role in its production.
The use of mustard seeds in cooking
Mustard seed is used worldwide, both whole and ground. In Europe, it's a classic ingredient in mustard and pickling spices, for example, in gherkins and herring. It's also frequently used in sausages, cheeses, and stews. In Indian and Middle Eastern cuisine, mustard seed is first roasted in oil, after which it imparts flavor to curries and sauces. Ground mustard seed forms the basis of wet mustards such as Dijon or Bavarian sweet mustard.
