Mustard

Mustard is a condiment made from the seeds of mustard plants, usually mixed with liquid such as water, vinegar, wine, or lemon juice to form a paste or sauce.

Mustard is a condiment made from ground mustard seeds mixed with liquid, salt, and spices. It is known for its pungent, tangy flavour and is a staple in cuisines worldwide.

What it is

Prepared mustard is produced by crushing, grinding, or using whole seeds from mustard plants (Sinapis alba, Brassica juncea, or Brassica nigra) and combining them with water, vinegar, wine, or lemon juice. The mixture is seasoned with salt and often additional spices, resulting in a paste or sauce that ranges from bright yellow to dark brown.

Why it matters

Mustard is one of the oldest condiments in Europe, with roots in ancient Roman use of ground seeds mixed with grape must. Its name likely comes from the Latin *mustum ardens*, meaning “burning must,” referring to its sharp heat. In Canada, mustard is a common table condiment, especially on sandwiches, burgers, and hot dogs, and is widely available in grocery stores.

Key details

The flavour varies by seed type and liquid: yellow mustard is mild and tangy, while brown and black seeds produce spicier versions. Mustard is used globally in dressings, sauces, marinades, and with meats, cheeses, and vegetables. Common varieties include white/yellow, brown/Indian, and black mustard.
