The Best Mustard Seed: Our Picks

Guide: Questions you should ask yourself before buying Mustard Seeds

What are mustard seeds?

Mustard seeds are small round seeds of the mustard plant that are used in spices, mustard products and remedies.

Mustard seeds are available ground as a powder, also called mustard flour, or as whole mustard seeds.

The black mustard seeds, also called brassica nigra, have a bitter, pungent taste. Dijon mustard, for example, is made from black mustard seeds.

The white mustard seeds of the mustard plant Sinapis alba are the most commonly used mustard seeds and, in contrast to the black seeds, taste rather mild and only slightly hot.

The brown mustard seeds(Brassica juncea) are often used in Indian cuisine. They are similarly hot as those of the black mustard plant.

Brown mustard seeds are used especially in sauces and spice mixtures.

Where do mustard seeds come from?

The mustard plant belongs to the cruciferous family and originally comes from the Near East and southern Europe.

The herbaceous plant of white mustard flowers yellow and grows up to one metre high, black mustard even higher. Shortly before the seeds in the pods of the plants are ripe, the mustard plant is mown and dried. The mustard is then threshed and the seeds are dried again.

The parable of the mustard seed in the New Testament shows that mustard seeds have been in use for a very long time. Mustard seeds were also used in ancient times as a spice and remedy for various diseases.

However, the fame of the mustard plant goes back to Charlemagne, who cultivated many spice plants on his land and began to process the mustard seeds into mustard. Nowadays, mustard is grown all over the world, but especially in Europe and the USA.

The mustard plant is cultivated especially in Germany, France and the Netherlands.

What flavour do mustard seeds have?

Mustard seeds consist of 36 percent nutty vegetable oil and essential oils. The essential oils contain the mustard oil glycosides, which are responsible for the pungency and flavour.

Mustard seeds in themselves are odourless and only develop their flavour when they come into contact with liquid. This is due to the enzyme myrosinase, which can only be activated by liquid. Through the activation of this enzyme, the mustard oil glycosides are transformed into various substances.

For example, those responsible for the pungency of the mustard seeds, such as isothiocyanates. The seeds of white mustard have a mild, nutty aroma at the beginning and become increasingly spicy in taste when chewed.

This phenomenon is due to the glycoside sinalbin, which is responsible for the pungency of the mustard seeds. The white mustard seeds harmonise well with chilli, pepper, tarragon, allspice, thyme and chervil. Mustard seeds are therefore often used in spice mixtures and also in marinades with other spices.

Black mustard seeds are sharper than the white ones and also have a bitter aroma. This is due to a different mustard oil glycoside mixture, in which the glycoside sinigrin is the decisive factor.

How are mustard seeds used?

Mustard seeds are available whole or ground and are mainly used as a condiment and for making table mustard. Whole mustard seeds are used in sausages, marinades for fish or meat and in pickled vegetables such as mixed pickles or gherkins.

Mustard powder is often used in sauces and soups, but also goes well with poultry and beef dishes. As a remedy, the mustard plant is used against joint pain, such as rheumatism and arthritis. But it is also used against muscle pain, headaches and backache.

Mustard seeds also stimulate the appetite and aid digestion. They can ensure good gastrointestinal activity.

How much do mustard seeds cost?

You can buy mustard seeds online for as little as 1.50 euros per 100 grams. Mustard seeds are available in 100 gram bags. If you need a larger quantity, you can also get them in 1 kilogram and even 5 kilogram bags.

Prices for ground mustard seeds, also called mustard flour, start at around 3.00 euros per 100 grams.

Type Price
whole dark mustard seeds from approx. 3,00€/100g
ground dark mustard seeds from approx. 4,00€/100g
whole light mustard seeds from approx. 2,00€/100g
ground light mustard seeds from approx. 2,50€/100g

What Types of Mustard Seeds are there and which is the right one for you?

To help you decide, we have listed the two most common types of mustard seeds with their advantages and disadvantages.

  • light mustard seeds
  • dark mustard seeds

What are light mustard seeds and what are their advantages and disadvantages?

Light mustard seeds are the better-known mustard seeds in Germany, although black mustard is more common worldwide and is used more often because it is sharper. The small yellow globules come from the mustard plant, which grows up to one metre high.

The light mustard seeds get their slightly pungent flavour from the mustard oil glycoside sinalbin, which is activated on contact with liquid. The light, yellow mustard seeds are used more frequently in Germany than the dark mustard seeds.

  • high nutrient content
  • versatile
  • only slightly spicy

They are often used in sausage and meat dishes. But the light mustard seeds are also very suitable for pickled vegetables. The ground light mustard is often used in spice mixtures and marinades and goes well with poultry.

Normal mustard is also made from the yellow mustard seeds. Mixed with water, vinegar and salt, the mustard flour becomes a paste known to us as mustard.

Mustard seeds also have a high vital substance content. They provide us with iron, magnesium, calcium, selenium, vitamin B1, vitamin B3 and vitamin E.

What are dark mustard seeds and what are their advantages and disadvantages?

Dark mustard seeds are the black and brown mustard seeds.

The difference between the black and the brown mustard seeds is only in the colour. The black and brown mustard seeds are very similar in taste, this is due to the mustard oil glycoside sinigrin, which causes the pungency and the slightly bitter taste.

Both types of mustard contain the glycoside sinigrin, which is why they are grouped together under dark or black mustard seeds. Black mustard originated in the Middle East and is also most commonly used there as a spice and in spice blends.

  • versatile
  • good pungency
  • somewhat more expensive than the light mustard

The best-known mustard made from black mustard seeds is Dijon mustard. The grains of dark mustard are somewhat smaller than those of yellow mustard and, like the light mustard seeds, are used as a spice and as a remedy.

The black mustard seeds are hotter than the light mustard seeds, which is due to the difference in pungency glycoside, and are widely used especially in Asian cuisine and in India.

As the processing of black mustard seeds is more complex than that of yellow mustard seeds, the seeds of the black mustard plant are rarer and therefore also somewhat more expensive than the white mustard seeds.

Buying Criteria: Use these Factors to compare and evaluate Mustard Seeds

In the following, we will show you which criteria you can use to compare and evaluate mustard seeds. This will make it easier for you to get an overview and decide on a suitable spice.

In summary, these are the following criteria:

In the following, you can read about the respective criteria and find out why it makes sense for you to purchase mustard seeds based on the criteria or not.


We have already introduced you to the different types of mustard seeds in the guide section.

A basic distinction is made between light and dark mustard seeds. The light mustard seeds, which can also have a yellow colour, are the seeds with the somewhat milder aroma.

They have a slightly nutty flavour at first and acquire a slightly pungent note when chewed and processed. The seeds of the yellow mustard plant are used in ground form, but also as a whole grain as a spice and often also in spice mixtures in the kitchen.

Dark mustard seeds refer to both brown and black mustard seeds. They are somewhat smaller than the light mustard seeds and differ from the light mustard seeds in colour.

Another difference is the pungency, which is clearly more intense in black mustard than in light mustard seeds.

The reason for this is the glycosides. The light mustard contains the somewhat milder glycoside sinalbin. Dark mustard gets its flavour from the glycoside sinigrin, which can become very hot when combined with liquid.


The mustard plant originally comes from the Near East and southern Europe. Nowadays, mustard plants are cultivated all over the world. They are especially cultivated in Germany, France and the Netherlands.

If you value organic quality, you should make sure that your mustard seeds come from Germany and are labelled with the organic quality seal.

Tip: You can also plant your own mustard plants in tubs or balcony boxes.

Take a few seeds and press them a few centimetres into the soil. Make sure that the soil is always slightly moist and that the plant gets some sun.


Prices for mustard seeds start at 2.00 euros per 100 grams. The price you end up paying also depends on what you want from the product.

Organic quality products are always more expensive and cost around 4.00 euros per 100 grams. The larger the quantity of mustard seeds you want to buy, the lower the price per 100 grams.

We have compiled an overview of the prices in the form of a table for organic mustard seeds:

quantity price
250g from €7.95
500g from €12.30
1000g from €18.95


The type of mustard seeds you buy also depends on what you want to use them for.

Black mustard seeds are hotter than light mustard seeds because of their glycoside sinigrin. If you only like the taste of mustard seeds, the light mustard seeds are sufficient.

If you want to give your food a nice spiciness and a delicious aromatic taste, then you should use the black mustard seeds.

Dark mustard seeds

Dark mustard seeds are more tart and traditionally form the basis of Dijon mustard in ground form. Dark mustard seeds are also mainly used in Asian and African cuisine.

In India, the dark mustard seeds are briefly sautéed and then added to the rest of the ingredients. The cooking of the mustard seeds creates a nutty aroma.

Black mustard is particularly suitable for spicy marinades, soups, meat and fish.

Light mustard seeds

Due to their somewhat milder flavour, they are used more often in German cuisine than black mustard. Light mustard is well suited for seasoning pickled vegetables and light fish sauces and meat sauces.

They are also often used in sausages and also to flavour salads, marinades and dressings. The yellow mustard plant is also the basis of table mustard.


The quality of mustard seeds is also important. You can recognise good mustard seeds by their size and colour. For light-coloured mustard seeds, you should take a look at the colour and size of the spheres. The colour and size should be uniform.

Dark mustard seeds vary in colour. They should be brown to black and also have an even size.

As already mentioned, you should always look for the organic quality seal. This ensures that the mustard seeds are untreated and come from Germany.

Companies that sell good quality also pay attention to the packaging. Look for resealable flavour bags so that the mustard seeds or mustard flour do not lose their flavour so quickly.

If you buy the mustard products in normal plastic bags, seal them well in a tin afterwards to retain the flavour and make them last as long as possible.

As a rule, mustard seeds should keep for about two years.

Facts worth knowing about Mustard Seeds

Mustard seeds as a remedy

Mustard seeds can provide relief from physical ailments.

They are

  • healing
  • anti-inflammatory
  • digestive
  • stimulates blood circulation

and can help with

  • Fungi
  • Viruses
  • Bacteria
  • Cancer
  • Joint diseases
  • Tension
  • Headaches and back pain
  • Muscle pain

According to medical studies, the mustard oil glycosides in the mustard seeds help against fungi, viruses and bacteria. The mustard plant has healing, anti-inflammatory, blood circulation and digestive properties.

It has also been proven that the mustard oil glycosides render carcinogenic substances harmless and can even block the development of tumours. Intestinal polyps, for example, can be reduced by 50 percent with mustard extract.

The anti-cancer effect of the mustard plant can be attributed to the isothiocyanates. They can help remove toxins from the organism. Mustard also helps the body to better digest fatty foods and counteract heartburn.

Mustard is also suitable for external use. Mustard baths, mustard ointments, mustard plasters and mustard compresses can promote blood circulation. That is why they are often used for joint diseases, but also for headaches, back pain and muscle aches.

But be careful: External applications should be done with special caution.

Especially on sensitive parts of the body, mustard should not be used for more than two weeks, as their heat development on the skin can cause redness and burns.

External applications with mustard are not recommended for kidney diseases and varicose veins!

Mustard leaves and sprouts

Not only the mustard seeds, but also the mustard leaves and the mustard shoots of the mustard plant are used as a spice or remedy because of their fresh taste and cleansing effect.

In Germany, the edibility of mustard leaves is less well known, although they can protect against diabetes if eaten regularly. In India, on the other hand, the leaves are often used in cooking. For example, they are cooked with garlic and onions and eaten together with naan bread.

Mustard sprouts are especially tasty in salads, in herb curd cheese or on fresh wholemeal bread and can promote human health with their high vital substances.

Religious significance of the mustard seed

The mustard seed is the object of a famous parable from the New Testament. It is one of the parables of growth, in which the contrast between a seed and a fully grown plant is placed in the centre.

The mustard seed stands for something very small, which in time can become something very big. The fact that the mustard seed is already mentioned in the New Testament shows that mustard plants were already used centuries ago.

Nowadays, it is assumed that the mustard seed in the parable is the seed of black mustard.
