Mustard (Brassica alba)

Mustard plants come in three main varieties: white, brown and black. Mustard seeds, mustard powder, mustard sprouts and mustard as a condiment are commonly used in many cuisines.


Mustard’s hot flavour is released once the seeds are crushed or mixed with water. White seeds have an initial sweetness and a milder flavour, brown seeds have an initial bitterness followed by a sharp biting flavour and black seeds are also sharp and pungent. When mustard seeds are fried, their taste turns from fiery to nutty.


Mustard seeds have little or no smell.


Mustard seeds, powder, spouts and condiments are used Indian, Asian and European (French in particular) cuisines.  Mustard pairs perfectly with mayonnaise, boiled eggs, cheese, cabbage, cauliflower, lentils, onion, artichokes, tarragon, basil, tomato, honey, champagne, turmeric, beef, ham and sausages.


Mustard plants can be started by seed all year round, except in areas of extreme cold winters. The plants are fast growing, growing to 1-3m, with bright yellow flowers that form the shape of a cross. The flowers form seed pods which shatter easily, so ensure you pick the pods before they are completely dry.

To make mustard sprouts, put about 2 tablespoons of mustard seeds in a muslin-covered glass jar. Rinse and drain the seeds once or twice a day until they sprout.


In the New Testament, Jesus told a parable of the mustard seed and Pythagoras suggested mustard paste as a treatment for scorpion stings. During the Middle Ages, mustard was introduced into Spain by Arab traders before being carried throughout Europe.


Mustard is sometimes used in a poultice to soothe muscular aches and inflammation. It has been known to stimulate the kidneys and digestive system. A gargle of mustard seed in hot water can be helpful for sore throats and bronchitis.
